DESCRIPTION

The HY64UD16322A is a 32Mbit 1T/1C SRAM

featured by high-speed operation and super low

power consumption. The HY64UD16322A adopts

one transistor memory cell and is organized as

2,097,152 words by 16bits. The HY64UD16322A

operates in the extended range of temperature and

supports a wide operating voltage range. The

HY64UD16322A also supports the deep power

down mode for a super low standby current. The

HY64UD16322A delivers the high-density low

power SRAM capability to the high-speed low power

system.
