Description
The HM62G18512 is a synchronous fast static RAM organized as 512-kword
×
18-bit. It has realized high
speed access time by employing the most advanced CMOS process and high speed circuit designing
technology. It is most appropriate for the application which requires high speed, high density memory and
wide bit width configuration, such as cache and buffer memory in system. It is packaged in standard 119-
bump BGA.
Note:
All power supply and ground pins must be connected for proper operation of the device.
Features
Power supply: 3.3 V +10%, –5%
Clock frequency: 200 MHz to 250 MHz
Internal self-timed late write
Byte write control (2 byte write selects, one for each 9-bit)
Optional
