MN4164P-12A DRAM 64K x1 Bit 120ns IC DIP-16

Description

MN4164P-12A DRAM 64K x1 Bit 120ns IC DIP-16 The MN4164P-12A is a single-chip dynamic RAM organized as 64K × 1 bit with a 120 ns access time, provided in a 16-pin DIP package. It implements the standard multiplexed row/column address scheme (RAS/CAS) used by early 64K DRAMs and is intended for use as general purpose byte-serial memory in small microcomputer and embedded systems designs. The device’s single-bit data path and simple control signals make it suitable where multiple devices are combined to form wider buses. Reads and writes are controlled with the RAS/CAS timing sequence; addresses are applied as a multiplexed pair (row then column). The device requires periodic refresh of stored data (via standard RAS-only or RAS/CAS refresh cycles) and provides an active I/O pin that floats when deselected. Typical timing and control requirements align with other 4164-class DRAMs (120 ns access characteristic). In practice the MN4164P-12A is used in small memory expansion banks or as part of multi-chip assemblies to create 8/16-bit wide modules. Its DIP-16 package makes it easy to prototype on breadboards or through-hole PCBs. For exact electrical limits, timing diagrams, and recommended refresh/operating conditions, refer to the scanned datasheet.
