What chip has Memory that is older and has a row of legs down each side of the chip?

Consider a 256x8 RAM chip a- How many 256x8 Ram chip are needed to provide a memory capacity of 4096 bytes b- How many bits will each memory address contain and address line must go to each chip?

a) To provide a memory capacity of 4096 bytes using 256x8 RAM chips, you need 4096 bytes / 256 bytes per chip = 16 chips. b) Each memory address for the 256 locations in a chip will require 8 bits (since 2^8 = 256). Therefore, each chip will require 8 address lines to select one of the 256 locations.

How many address lines are needed to address each machine location in a 2048 X 4 memory chip?

It depends on how wide the data buses are on each chip, and how they're connected. If they're one byte wide, you could need over 256 million addresses, one for each byte. if they're wider, and connected to show an even wider combined data bus, it could be much less; around 32 million.

How many number of registers and memory cells in a 128 x 4 memory chip?

A 128 x 4 memory chip consists of 128 rows and 4 columns. Each column corresponds to a memory cell, so there would be a total of 4 memory cells. In terms of registers, it would depend on the organization of the memory chip - typically, there would be additional registers for addressing, data input/output, and control signals.

How many memory location could be directly accessed in a ram chip which is connected?

The number of memory locations that can be directly accessed in a RAM chip depends on its size and architecture. For example, a 1 GB RAM chip typically has 2^30 (1,073,741,824) memory locations if each location holds 1 byte. The total number of directly accessible locations is determined by the addressing scheme, which is usually defined by the number of address lines in the chip.

How text sound pictures and video files are stored in a computer's memory?

with electrical signals sent to each bit of the memory chip. a common memory chip in a PC dumps data when shut off. on other devices like USB drives the data doesn't. also the wattage on a video and audio card determines the frequency it is emulated.

How does data get on the microchip after manufacturing?

Well, honey, after the microchip is manufactured, data is typically programmed onto it using specialized equipment that can write and read information to and from the chip. This process is usually done in a controlled environment to ensure accuracy and reliability. So, in a nutshell, data gets on the microchip after manufacturing by writing it onto the chip using fancy machines.

What is memory address register?

Whenever anything is stored in the memory of your computer (RAM) it is stored at a specific place. Each specific place in your memory has its address that can be used to tell computer programs to go to those addresses to perform actions on the object stored at that address. It is similar to how you have your house number.

Stamped on each chip of a ram module is a blank that identifies the date the chip was manufactured?

Chip ID

What is semiconducter memories?

Definition: A device for storing digital information that is fabricated by using integrated circuit technology. Also known as integrated-circuit memory; large-scale integrated memory; memory chip; semiconductor storage; transistor memory. Semiconductor memory is an electronic data storage device, often used as computer memory, implemented on a semiconductor-based integrated circuit. Examples of semiconductor memory include non-volatile memory such as Read-only memory (ROM), magnetoresistive random access memory (MRAM), and flash memory. It also includes volatile memory such as static random access memory (SRAM), which relies on several transistors forming a digital flip-flop to store one bit, and dynamic random access memory (DRAM), which uses one capacitor and one transistor to store each bits. Shift registers, processor registers, data buffers and other small digital registers that have no memory address decoding mechanism are not considered as memory. Data is accessed by means of a binary memory address to the memory. If the memory address consists of M bits, the address area consists of two raised by M addresses per chip. Semiconductor memory are manufactured with a certain word length (number of 1-bit cells sharing the same memory address) that power of two, typically M=1, 2, 4 or 8 bit per chip. Consequently, the amount of data stored in each chip is MN2 bits. Possible figures are 1, 2, 4, 8, 16, 32, 64, 128, 256 and 512 bit, kbit, Mbit, Gbit and Tbit, here defined by binary prefixes. By combining several integrated circuits, memory can be arranged for a larger word length and/or address space than what is offered by each chip, often but not necesserily a power of two.

What are the Memory types used in the 8051 microcontroller?

The memory types are : On-Chip Memory, External Code Memory, and External RAM.On-Chip Memory refers to any memory (Code, RAM, or other) that physically exists on the microcontroller itself. On-chip memory can be of several types, but we'll get into that shortly.External Code Memory is code (or program) memory that resides off-chip. This is often in the form of an external EPROM.External RAM is RAM memory that resides off-chip. This is often in the form of standard static RAM or flash RAM.Code MemoryCode memory is the memory that holds the actual 8051 program that is to be run. This memory is limited to 64K and comes in many shapes and sizes: Code memory may be found on-chip, either burned into the microcontroller as ROM or EPROM. Code may also be stored completelyoff-chip in an external ROM or, more commonly, an external EPROM. Flash RAM is also another popular method of storing a program. Various combinations of these memory types may also be used--that is to say, it is possible to have 4K of code memory on-chip and 64k of code memory off-chip in an EPROM.When the program is stored on-chip the 64K maximum is often reduced to 4k, 8k, or 16k. This varies depending on the version of the chip that is being used. Each version offers specific capabilities and one of the distinguishing factors from chip to chip is how much ROM/EPROM space the chip has.However, code memory is most commonly implemented as off-chip EPROM. This is especially true in low-cost development systems and in systems developed by students.External RAMAs the name suggests, External RAM is any random access memory which is found off-chip. Since the memory is off-chip it is not as flexible in terms of accessing, and is also slower. For example, to increment an Internal RAM location by 1 requires only 1 instruction and 1 instruction cycle. To increment a 1-byte value stored in External RAM requires 4 instructions and 7 instruction cycles. In this case, external memory is 7 times slower!What External RAM loses in speed and flexibility it gains in quantity. While Internal RAM is limited to 128 bytes (256 bytes with an 8052), the 8051 supports External RAM up to 64K.On-Chip MemoryAs mentioned at the beginning of this chapter, the 8051 includes a certain amount of on-chip memory. On-chip memory is really one of two types: Internal RAM and Special Function Register (SFR) memory.the 8051 has a bank of 128 bytes of Internal RAM. This Internal RAM is found on-chip on the 8051 so it is the fastest RAM available, and it is also the most flexible in terms of reading, writing, and modifying its contents. Internal RAM is volatile, so when the 8051 is reset this memory is cleared.The 128 bytes of internal ram is subdivided as shown on the memory map. The first 8 bytes (00h - 07h) are "register bank 0". By manipulating certain SFRs, a program may choose to use register banks 1, 2, or 3. These alternative register banks are located in internal RAM in addresses 08h through 1Fh.Bit Memory also lives and is part of internal RAM. We'll talk more about bit memory very shortly, but for now just keep in mind that bit memory actually resides in internal RAM, from addresses 20h through 2Fh.The 80 bytes remaining of Internal RAM, from addresses 30h through 7Fh, may be used by user variables that need to be accessed frequently or at high-speed. This area is also utilized by the microcontroller as a storage area for the operating stack. This fact severely limits the 8051s stack since, as illustrated in the memory map, the area reserved for the stack is only 80 bytes--and usually it is less since this 80 bytes has to be shared between the stack and user variables.

Explain how to check that chips on a video card are properly seated in their sockets?

While properly grounded (to prevent static electricity buildup and damage to the electronic components) gently push downward on the chip. Added 1 Dec 08: Remove the card from the expansion slot and use a screwdriver to press down firmly on each corner of each socketed chip on the card. Chips sometimes loosen because of thermal changes; this condition is called chip creep. pg. 422

Can you reset the chip on a HP toner cartridge yourself?

Remanufacturers used to be able to reset the older HP chips, for example the 1300, 2300, 1320, 1160 and etc. But at the speed that new chipped cartridges are coming out and with HP going to the new smaller chips, the industry as a whole as pretty much abandon trying to keep up the technology to research and reset each chip. There are a few that have held on to the old chip reseters to reset the older style I mentioned earlier, but the vast majority simply replace the chips with new ones. It is easier, faster, cheaper and will cut down on the chance of defective cartridges because of bad resets.
