#### Descriptions:

The TMS4256-12NL is a 256K dynamic RAM (DRAM) chip from Texas Instruments, organized as 64K words by 4 bits. It operates with a single +5V power supply and features a 120 ns access time. This NMOS-based memory chip is designed for use in early computer and embedded systems requiring moderate-speed DRAM storage.

#### Features:

  • 64K x 4 organization
  • Single +5V power supply
  • 120 ns access time (TMS4256-12NL)
  • 18-pin DIP package
  • Dynamic refresh required (typical 2ms refresh interval)
  • Fully static operation possible with RAS-only refresh
  • TTL-compatible inputs and outputs
  • Low power consumption in standby mode

This part is now considered obsolete but was widely used in vintage computing and industrial applications.
