description and is subject to change without notice. Hynix Semiconductor Inc does not assume any responsibility for use of circuits described. No patent licenses are implied. Rev.01 /Mar.2002 Hynix Semiconductor Preliminary DESCRIPTION The HY62UF16804B is a high speed, super low power and 8Mbit full CMOS SRAM organized as 512K words by 16bits. The HY62UF16804B uses high performance full CMOS process technology and is designed for high speed and low power circuit technology. It is particularly well-suited for the high density low power system application. This device has a data retention mode that guarantees data to remain valid at a minimum power supply voltage of 1.2V.
