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.","metaTitle":"TI SMJ4161-20JDS Video DRAM, 64Kx1, 200 ns NMOS","metaDescription":"Texas Instruments SMJ4161-20JDS video DRAM, 64Kx1 organization, 200 ns access time, NMOS technology.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"series":"*","package_type":"Bulk","product_status":"Active","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.81","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e55fcd9b5cd6b6380df8e392317f8164.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the SMJ4161-20JDS used for?","answer":"It is a 64Kx1 video DRAM with 200 ns access time, built on NMOS technology.
