both are semiconductor memory. semiconductor means that both need continuous voltage or charge to sustain their data.
SRAM used for cache , and store data in the flip flop, no need for refreshing , fast access but more expensive.
DRAM used for main memory , and store data in capacitor, need for refreshing , slow access but less expensive.
What else can I help you with?
How would you write about SRAM?
---SRAM--- Static random access memory (SRAM) is a type of semiconductor memory where the word static indicates that it, unlike dynamic RAM (DRAM), does not need to be periodically refreshed, as SRAM uses bistable latching circuitry to store each bit. SRAM exhibits data remanence, but is still volatile in the conventional sense that data is eventually lost when the memory is not powered. The term SDRAM, which stands for synchronous DRAM, should not be confused with SRAM.
What are the two senses in which the term random access memory is used?
due to permanent storage
Is dram a short temr memory?
Yes, DRAM is a short term memory. It is Dynamic RAM, which means when the power goes off, it looses its contents. SRAM would be Static RAM, which means it saves its memory contents after power supply has stopped.
What is the difference between DRAM and SRAM?
Short for static random access memory, and pronounced ess-ram. SRAM is a type of memory that is faster and more reliable than the more common DRAM (dynamic RAM). The term static is derived from the fact that it doesn't need to be refreshed like dynamic RAM. To store 1 bit of information about 6 transistors are used and it does not required refreshing. Because Six transistors are used to store 1 bit of information, it is more costlier than DRAM in terms of cost per bit, where only 1 transistor and 1 capacitor is used to store 1 bit of information.DRAM stands for dynamic random access memory, a type of memory used in most personal computers. In DRAM to store 1 bit of information 1 transistor and 1 capacitor is used. The information is stored in the capacitor in form of charge, so it required refreshing to retain the charge or data in the capacitor.SRAM is Static RAM and DRAM is Dynamic RAM. DRAM is slower than SRAM and needs to be refreshed where SRAM does not and is used for cache.(Static RAM) SRAM is similar to DRAM but does not constantly refresh. SRAM is faster and more expensive than DRAM and is generally used for speed-critical areas of the computer such as cache memory.(Dynamic Random Access Memory) DRAM is the most common type of memory and is "dynamic" because in order for the memory chip to retain data, it must be refreshed constantly (every few milliseconds). If the cell is not refreshed, the data is lost. DRAM temporarily stores data in a cell composed of a capacitor and a transistor. Each cell contains a specified number of bits. These cells are accessed by row addresses and column addresses.
Why sram is called static ram?
Static random-access memory (SRAM) is a type of semiconductormemory that uses bistable latching circuitry to store each bit. The term staticdifferentiates it from dynamic RAM (DRAM) which must be periodically refreshed. SRAM exhibits data remanence,[1]but it is still volatilein the conventional sense that data is eventually lost when the memory is not powered.
What is the difference of sram and dram in terms of application?
DRAM is made with cells that store data as charge on capacitors. The presence or absence of charge on a capacitor is interpreted as a binary 1 or 0. Because capacitors have a natural tendency to discharge, dynamic RAMs require periodic charge refreshing to maintain data storage. The term dynamic refers to this tendency of the stored chrage to leak away, even with power continuously applied.SRAM is a digital device, using the same logic elements used in the processor. In a SRAM, binary values are stored using traditional flip-flop logic-gate configurations. A static RAM will hold its data as long as power is supplied to it.by: donaldpelaez@yahoo.com

Is dram volatile?
Yes, dram (Dynamic Random Access Memory) is considered volatile memory because it requires a constant power supply to retain data. Once the power is turned off, all information stored in DRAM is lost. This characteristic makes it suitable for temporary data storage while a device is powered on, but not for long-term data retention.

What Most common memory technology used in today computers?
There are actually several. I'll cover them all. RAM (Random Access Memory) is the most common memory type in use for any, general purpose functionality. This is due to it's cheap manufacture, relatively high speed, reliability, and accessibility. RAM can be written to, read from, and erased rapidly without trouble. Other types may be Read Only, or may not be able to be written to on demand, or may have other unusual features that make it undesireable for specific applications. DRAM (Dynamic RAM) is the most common individual RAM technology. There are MANY kinds, which I'll name later. It can read, write, and be erased easily and quickly. It is cheap to manufacture, and pretty reliable. However, it uses more power than some other kinds, and loses it's information if power is lost. RAM can reach speeds of up to 12,800 megabytes per second, depending on technology, frequency, and latency. Types of DRAM: FP-RAM, EDO RAM, BEDO RAM, SDRAM, RDRAM/Rambus, DDR, DDR2, DDR3, Window Ram, Bubble RAM, GDDR, GSDR, GDDR2, GDDR3, GDDR4, GDDR5, XRAM, XDRAM, RTRAM, (some) vacuum tubes, etc. Static RAM and Cache RAM are used typically inside processors. SRAM (Static RAM) is much faster and smaller than DRAM, but also more expensive. It does NOT lose information if power is lost (however CPUs typically clear SRAM for reliability reasons.) SRAM is usually in sizes of 8 MB or less, and used for specific tasks. SRAM can reach as high as 32,000 megabytes a second. SRAM is the most reliable method of memory in existence as of now, which it has to be as it's under constant, heavy use even when the CPU is idle. A CPU's Cache SRAM may move as much as 1 TB (1 terabyte) per day! With a tolerance of *zero*, that means it has to be accurate every single time, or an error will result. Types of SRAM: SRAM, Cache, Buffer, Core Memory, (some) Vacuum Tubes, Mercuric Memory, Magnetic Memory, Delay Line Memory, etc. There are also types of ROM (Read Only Memory) which can only be read from, typically. PROM (Programmable ROM) can be written to only under special situations, typically during their initial manufacture, and cannot be changed by the system. PROM is permanent memory data, meaning it doesn't disappear without power even after a long period of time. EEPROM (Electronically Eraseable ROM) can be erased electrically, including by the computer, and written to again in a single sequential block. CMOS/BIOS, Firmware, etc. typically use this to store data. The fastest EEPROMs and PROMs can push 200 MB/s. EEPROM and PROM are typically used for read-only functions, and as such, can be considered almost totally reliable for read tasks. Flash and SD memory are types of PRAM (Programmable Random Access Memory). They use an electrical means to randomly read, write, and erase data. They can also be used for storage, such as Flash Cards, XD cards, Memory Sticks, USB Thumb Drives, and Solid State Drives. The fastest Flash and SSDs can push 2,000 MB/s. Most mp3 players and portable media players use Flash and SSD to store music and data, as it's smaller and faster than small HDDs. Flash and SD are also less reliable than DRAM and SRAM. Virtual Memory is a term used to denote a storage device being used as RAM. Anything that can read/write randomly can be used as RAM, so many computers use Hard Drives to temporarily store data, usually to conserve DRAM or if the system runs out of DRAM. Hard drives are MUCH slower than DRAM, SRAM, and as of this writing, can push a maximum sustained rate of 120 MB/s. As such, this is not a desireable method of memory storage. The advantage is that Hard Drives are very, very large and quite inexpensive. However they are also far less reliable than DRAM and SRAM.
What is the difference between whole life insurance versus term life insurance?
Term life insurance is an insurance that is set for a specific time period, for example, one can obtain term life insurance for 30 years. Whole life insurance covers one from application to death.
