Between SRAM and DRAM
Difference Between SRAM and DRAM :
The difference between SRAM and DRAM is as follows:
SRAM:
1. It is faster than DRAM.
2.IT is more expensive.
3.It does not need to be power refreshed.
4.It utilize less power.
5.It holds data identified as long as the computer is turned on.
6.It is more complex and less compact.
DRAM;
1. It is slower than SRAM.
2.It is less than expensive.
3. It has to be refreshed after each read operation.
4. It utilizes more power.
5. It holds data dynamically not indefinitely.
6.It is less complex and more compact.
Memory Module;
Memory Module are small circuit boards that hold RAM chips. These modules into memory slots on the motherboard. Most personal computers have slots for two to four memory modules. They come in different sizes and have different pin configurations.
Two types of memory modules are as follows:
SIMM:
SIMM stands for Single Inline Memory Module. It is an older standard of RAM memory module. It was developed in 1983 at Wang Laboratories. It was used in old computers during 1980s and 10990s. The SIMM module has 72 pins and it only supports 32-bit data. The typical SIMM module is 4.25 inches in length and 1 inch in width.
DIMM:
DIMM stands for Dual Inline Memory Module. It provides faster data transfer speed and better features. It typically supports 64-bit data transfer.
The most common pin configuration of DIMM module in 168 pins. Some other DIMM configurations are 100, 172, 184, 204, 214 and 240 pins. DIMM has a physical size of 1.67 to 5.25 inches in length and 1 to 1.75 inches in width. Most desktop computers today use DIMM. The note book computers typically use a smaller type of memory module known as a small outline DIMM (SO- DIMM).
