GENERAL DESCRIPTION
The K6X4008T1F families are fabricated by SAMSUNG′s
advanced full CMOS process technology. The families support
various operating temperature range and have various package
types for user flexibility of system design. The families also sup-
port low data retention voltage for battery back-up operation
with low data retention current.
