With the rapid development of microelectronics technology, SRAM gradually presents the development trend of high integration, fast and low power consumption. In the development of semiconductor memory, SRAM has become an indispensable and important member because of its wide application.
The most important feature of the RAM is that it can be read and written at any time, but when the power is disconnected, the stored information will disappear. The data storage mode of SRAM relies on a pair of inverters connected in a closed-loop form of storage circuit, its code reading is non-destructive, does not need the corresponding refresh circuit, so its access speed is faster than DRAM. But SRAM requires more transistors to store one bit of information (six or four or two cells), so its bit density is lower than other types and costs more to build. SRAM is mostly used for level 2 caching.
This paper introduces an EMI 1Mbit asynchronous low power SRAM chip EMI501HB08PM-55i made in China. The product is manufactured by EMI advanced CMOS technology. Support industrial temperature range -40℃~85℃. EMI501HB08PM-55i adopts 32SOP chip package, and the power supply voltage is 4.5V~5.5V, so as to realize the user flexibility design of the system. Low data retention voltage is also supported for battery backup operations with low data retention current.
