128Kx8 bit Super Low Power and Low Voltage full CMOS Static RAM
GENERAL DESCRIPTION
The K6X1008T2D families are fabricated by SAMSUNG
s
advanced CMOS process technology. The families support
verious operating temperature ranges and have various pack-
age 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.
FEATURES
Process Technology: Full CMOS
Organization: 128K x 8
Power Supply Voltage: 2.7~3.6V
Low Data Retention Voltage: 1.5V(Min)
Three state outputs
Package Type: 32-SOP-525, 32-TSOP1-0820F
32-SOP-525, 32-TSOP1-0820F
PRODUCT FAMILY
1. This parameter is measured in the voltage range of 3.0V~3.6V with 30pF test load.
