GENERAL DESCRIPTION
The K6T4016V3B and K6T4016U3B families are fabricated by
SAMSUNG′s advanced CMOS process technology. The fami-
lies support various operating temperature range and have
small 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.
