CMOS SRAM
128Kx8 bit Super Low Power and Low Voltage full CMOS Static RAM
FEATURES
GENERAL DESCRIPTION
• 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
The K6X1008T2D families are fabricated by SAMSUNG′s
advanced CMOS process technology. The families support
verious 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.

1. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output voltage
levels.
2. At any given temperature and voltage condition, tHZ(Max.) is less than tLZ(Min.) both for a given device and from device to device
interconnection.

NOTES (WRITE CYCLE)
1. A write occurs during the overlap of a low CS1, a high CS2 and a low WE. A write begins at the latest transition among CS1 goes low,
CS2 going high and WE going low: A write end at the earliest transition among CS1 going high, CS2 going low and WE going high,
tWP is measured from the begining of write to the end of write.
2. tCW is measured from the CS1 going low or CS2 going high to the end of write.
3. tAS is measured from the address valid to the beginning of write.
4. tWR is measured from the end of write to the address change. tWR applied in case a write ends as CS1 or WE going high tWR2 applied
in case a write ends as CS2 going to low.
