The K6X4008C1F families are fabricated by SAMSUNGs advanced full CMOS process technology. The families supports various operating temperature range and various package types for user flexibility of system design. The families also support low data retention voltage for battery backup operation with low data retention current.

CMOS Static RAM (SRAM) is a type of computer memory that uses Complementary Metal-Oxide-Semiconductor (CMOS) technology to store digital information.

Unlike dynamic RAM (DRAM) which needs to be constantly refreshed to maintain data, SRAM retains data as long as power is supplied to it. This makes SRAM faster and more reliable than DRAM, although it is also typically more expensive and requires more power.


· Process Technology: Full CMOS
· Organization: 512Kx8
· Power Supply Voltage: 4.5~5.5V
