KM68V1000B, KM68U1000B Family CMOS SRAM
128K x8 bit Low Power and Low Voltage CMOS Static RAM
FEATURES
• Process Technology : Poly Load
• Organization : 128Kx8
• Power Supply Voltage :
KM68V1000B family : 3.0~3.6V
KM68U1000B family : 2.7~3.3V
• Low Data Retention Voltage : 2V(Min)
• Three state output and TTL Compatible
GENERAL DESCRIPTION
The KM68V1000B and KM68U1000B families are fabricated
by SAMSUNG′s advanced CMOS process technology. The
families support various operating temperature ranges and
have various package types for user flexibility of system
design. The families also support low data retention voltage for
battery back-up operation with low data retention current.
• Package Type : 32-SOP, 32-TSOP1-0820F/R
