GENERAL DESCRIPTION
The K6T1008C2E families are fabricated by SAMSUNG′s
advanced CMOS process technology. The families support
various 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.
