Marks 2. Unlike dynamic RAM, it does not need to be refreshed. © 2007-2021 Transweb Global Inc. All rights reserved. Static random access memory (SRAM) can retain its stored information as long as power is supplied. For example, 4*4 RAM memory can store 4 bit of information. A value is read by precharging the bit lines to a value 1/2 way between a 0 and a 1, while asserting the word line. This is in contrast to dynamic RAM (DRAM) where periodic refreshes are necessary or non-volatile memory where no power needs to be supplied for data retention, as for example flash memory. It is relatively faster than other RAM types such as DRAM.
