Static Random Access Memory (SRAM) stores data and instructions temporarily to be accessed at random by the computer processor. Its chip uses only transistors and no capacitors, which prevents the leakage and data corruption often caused by the older dynamic RAM (DRAM). It has an access time as low as 10 nanoseconds and a cycle time much shorter than in a DRAM since it does not pause between accesses. However, because its production is much more expensive than a DRAM, it is commonly used as a memory cache only.
Types of SRAMs
Kinds of SRAMs include the following:
Asynchronous SRAM
Asynchronous SRAM works separately from the system clock of the computer’s CPU. It features a chronological READ and WRITE pattern.
Synchronous SRAM
Synchronous SRAM is coordinated with the system clock, which reduces delay and increases speed. It features an overlapping READ and WRITE pattern.
Pipeline burst SRAM
A pipeline burst SRAM is the most popular type of SRAM. It can operate on bus speeds over 66 MHz.
Choosing SRAMs (Buying tips)
Memory capacity: Choose an SRAM with a large capacity if you use heavy applications or operate several programs simultaneously. Generally, a capacity of 64 MB and below is considered low-end, 128 MB to 256 MB are mid-range, and 512 MB and above are high-end.
