SRAM is one of random access memories. SRAM has three different modes supported. Each function is described below with Truth Table. STANDBY MODE Device enters standby mode when deselected (CS1# HIGH or CS2 LOW). The input and output pins (I/O0-7) are placed in a high impedance state. CMOS input in this mode will maximize saving power. WRITE MODE Write operation issues with Chip selected (CS1# LOW and CS2 HIGH) and Write Enable (WE#) input LOW. The input and output pins (I/O0-7) are in data input mode. Output buffers are closed during this time even if OE# is LOW. READ MODE Read operation issues with Chip selected (CS1# LOW and CS2 HIGH) and Write Enable (WE#) input HIGH. When OE# is LOW, output buffer turns on to make data output. Any input to I/O pins during READ mode is not permitted. In the READ mode, output buffers can be turned off by pulling OE# HIGH. In this mode, internal device operates as READ but I/Os are in a high impedance state. Since device is in READ mode, active current is used. TRUTH TABLE.
