· Static RAM: No refreshing, 6 to 8 MOS transistors · Dynamic RAM: Refreshed periodically, 3 to 4 transistors. · Static ram is more reliable · Dynamic ram is less reliable · Static ram is more expensive · Dynamic ram is less expensive · Static ram can store its data when computer is turned off · Dynamic ram looses data when computer is turned off. · A static memory cell takes a lot more space on a Chip than a dynamic memory cellby syed9230088668199
SRAM (Static RAM) and DRAM (Dynamic RAM)
What is the diferences between statis ram and dynamic RAM
Static RAM is fasterAnswerStatic Ram, SRAM Is Cache memory and Dynamic Ram, DRAM is main memory.Dynamic Ram consists of one transistor and two capacitors there for this needs to be constantly refreshed there for slower than static ram as for Static Ram this has 6 transistors which deal in transistor 1's and 0's on and off's this means it does not need to be refreshed there for much faster than dynamic ram Static Ram sits between the central processing unit and the main memory.
Static, and Dynamic.
The dynamic memory is formed of MOSFET and capacitor only. Hence it it is less bulkier than static RAM.
In terms of computing history, some types of RAM that have been used are:Williams-Kilbern CRT dynamic RAMSelectron Tube static RAMWhirlwind Floodgun Tube static RAMMagnetic Core nonvolatile static RAMMagnetic Thinfilm nonvolatile static RAMMagnetic Plated Wire nonvolatile static RAMSolidstate IC static RAM*Solidstate IC dynamic RAM*Magnetic Solidstate IC nonvolatile static MRAMNote: * These are the most common RAM in use today.
static RAM:It is composed of registers ,which loses its content when power is switched off.dynamic RAM:It is composed of capacitors,which is a charging and discharging in nature.
memory cache is a small amount of RAM (referred to as static RAM) that is much faster than the rest of the RAM, which is called dynamic RAM (DRAM).
I am not to sure about Static Ram but in CMOS RAM, 1GB of RAM would contain about 137438953472 transistors because 1 bit of CMOS RAM contains 16 Transistors, 8 bits in a byte and 1073741824 bytes in a gigabyte. I am 100% sure about this and these are just estimations. Static RAM uses about 6 times as many transistors as dynamic RAM for the same amount of storage. Dynamic RAM uses 1 or 2 transistors per bit in typical implementations. Add to this transistors for address decode, bus interface, etc.
SRAM does not need to be refreshed; basically it does have data remance although still volatile. Since it does not need to be refreshed it is better than dynamic ram, which needs to be refreshed periodically.
SRAM (static RAM).1. Memory maintains data in storage as long as it is powered. Because it is faster and more reliable and expensive than DRAM, SRAM is most often used as cache memory. Earlier forms of SRAM were classified as Async or Sync RAM if they were synchronized with the system clock.2. The most common type of SRAM today is pipeline burst SRAM, which can operate at higher bus speeds.DRAM (dynamic RAM).1.This type of RAM retains its data by being continuously rewritten every few milliseconds. Like SRAM, the data in storage is volatile, meaning it is lost when the system is not powered.2. DRAM is the most common type of expandable company memory in workstations and servers today, but there are several different types of DRAM.3. The advantage of DRAM is its structural simplicity: only one transistor and a capacitor are required per bit, compared to four transistors in SRAM. This allows DRAM to reach very high density. Also DRAM is also cheaper than SRAM.
