2 / 9 page KM6161002B, KM6161002BI CMOS SRAM Rev 2.0 - 2 - February 1998 PIN FUNCTION Pin Name Pin Function A0 - A15 Address Inputs WE Write Enable CS Chip Select OE Output Enable LB Lower-byte Control(I/O 1~I/O8) UB Upper-byte Control(I/O 9~I/O16) I/O1 ~ I/O16 Data Inputs/Outputs VCC Power(+5.0V) VSS Ground N.C No Connection 64K x 16 Bit High-Speed CMOS Static RAM The KM6161002B is a 1,048,576-bit high-speed Static Random Access Memory organized as 65,536 words by 16 bits. The KM6161002B uses 16 common input and output lines and has at output enable pin which operates faster than address access time at read cycle. Also it allows that lower and upper byte access by data byte control ( UB, LB). The device is fabricated using SAMSUNG ′s advanced CMOS process and designed for high-speed circuit technology. It is particularly well suited for use in high-density high-speed system applications. The KM6161002B is packaged in a 400mil 44-pin plastic SOJ or TSOP2 forward.
