HM4864P-2: 64k x 1-Bit NMOS Monolithic Dynamic Random-Access Memory (DRAM) IC, featuring a high-speed 150-nanosecond random address access time index. Operating from a single +5V power distribution rail, it coordinates stable data caching, register expansion tracks, and memory refresh cycles across legacy personal computers (such as classic Apple IIe and IBM PC/XT architectures), housed in an industry-standard 16-pin through-hole plastic dual in-line package (PDIP-16) layout. Manufactured by Hitachi.
