The HM62G18512 is a synchronous fast static RAM organized as 512-kword x 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 119bump BGA. Note: All power supply and ground pins must be connected for proper operation of the device.
