GENERAL DESCRIPTION
The K6X4008C1F families are fabricated by SAMSUNG′s
advanced full CMOS process technology. The families sup-
ports various operating temperature range and various
package types for user flexibility of system design. The fam-
ilies also support low data retention voltage for battery back-
up operation with low data retention current.
