Product details

Video DRAM for legacy frame-buffer designs

The Texas Instruments SMJ4161-20JDS is a 64Kx1 video DRAM built on NMOS technology, with a 200 ns access time. It is designed for use in video frame buffers and graphics memory subsystems where a single-bit-wide, moderate-speed DRAM interface is required. The part is (typically tubes or trays), not tape-and-reel, so plan for manual or tube-fed placement.

Sourcing posture: active, no last-time-buy pressure

There is no announced last-time-buy or end-of-life notice, so you can commit this part to the BOM without near-term obsolescence risk.

The 200 ns access time sets the minimum read/write cycle window. In a video frame-buffer application, this governs the pixel clock rate the controller can support without wait states. A faster DRAM (e.g., 120 ns) would relax timing margins, but if your existing controller and PCB layout are tuned for 200 ns, this part meets the spec without redesign.

Frequently asked questions

What is the SMJ4161-20JDS used for?

It is a 64Kx1 video DRAM with 200 ns access time, built on NMOS technology. Typical applications include video frame buffers, graphics memory, and other single-bit-wide DRAM subsystems in legacy or industrial video equipment.

What is the closest pin-compatible alternative to the SMJ4161-20JDS?

For a direct replacement, verify the footprint and timing against other 64Kx1 DRAMs in the same package; the active lifecycle means the original part remains available for new builds.
