How many chips with 12 address buses and 4 data buses are needed for 16k memory is needed.?

if we have 10 address bits then we can have a memory module of
2^10 = 1024 b = 1kb
so for 16kb we need
16*2^10 = 2^14=16kb
here we need 2 chips as 1 chip only provid us 2^12 memory.
Address and data bus are multiplexed to reduce complexity.

How many lines of the address must be used to access 2048 bytes. How many of these lines are connected to the address input of all chips?
That depends on the memory architecture of the system.if the memory chips are byte wide and not used to create a multibyte bus, 11 address bits are needed.if the memory chips are 32 bits wide, 9 address bits are needed (with the CPU internally selecting which of the 4 bytes it will use).it the memory chips are 64 bits wide, 8 address bits are needed (with the CPU internally selecting which of the 8 bytes it will use.if the memory chips are 4 bits wide, 12 address bits will be needed and the CPU must perform 2 memory cycles per byte that it needs. (yes, I have seen a computer that worked this way!)etc.
What is an address buffer and a data buffer?
The contents of the stack pointer and program counter are loaded into the address buffer and address-data buffer. These buffers are then used to drive the external address bus and address-data bus. As the memory and I/O chips are connected to these buses, the CPU can exchange desired data to the memory and I/O chips. The address-data buffer is not only connected to the external data bus but also to the internal data bus which consists of 8-bits. The address data buffer can both send and receive data from internal data bus.
How many 128 8 memory chips are needed to provide a memory capacity of 4096 16?
64
How many address lines are necessary to access 2k x 8 memory system using 256 x 8 memory chips?
Why do you want to waste 99.22% of the memory in these chips you supposedly will be spending good money on? Buy smaller sized memory chips more suitable for your purposes and design with them!
How many 2147 RAM memory chips are needed to configure a 4K X 8 memory?
The 2147 memory is 4096 X 1 bit static RAM. You need 8 chips to form 4K x 8.
How many address lines are necessary to access 64K x 8 memory system using 8K x 8 memory chips?
14 lines can address 16,384 locations. The 8085, however, has 16 lines, and can address 65,536 locations.The system design, of course, may limit that to 14, so 16,384 is the answer in that case.
Memory usually consists of one or more chips on this?
Memory usually consists of one or more chips of bytes.
After you've installed custom firmwire can you use your normal memory stick?
Yes, the custom firmware is all stored on the PSP's internal chips and memory, you can do what you want with the memory card you used to install it, it is no longer needed, and you can replace it with your regular memory card.
What is the difference between sam and ram?
In RAM ,the access time is the same for any memory location.Semi-conductor IC chips and magnetic disks are random access memory.In SAM a particular memory word is accessed from the memory by going through all address locations until the desired address is found.Magnetic tapes are sequential access memory.
What are components of an integrated circuit?
Integrated circuits are comprised of transistors and diodes interconnected in different ways via conductors to perform the desired functions. In some cases resistors may be deposited as part of the circuit.
What consists of nonvolatile memory chips that can be used for storage by the computer or the user?
Flash memory consists of nonvolatile memory chips that can be used for storage by the computer or the user. Flash memory was introduced in 1984.
What are Memory chips that store permanent data and instructions- the data cannot be modified?
chips with memories are worrying. don't eat them or they will lose their memory!
