The Texas Instruments TMS44409-70DJ is a 4Mbit EDO DRAM with a memory organization of 1Mx4. This component offers a maximum access time of 70ns and operates with a supply voltage range of 4.5V to 5.5V, typically 5V. It supports Fast Page mode with EDO extensions and features RAS-only, CAS-before-RAS, and hidden refresh capabilities with 1024 refresh cycles. The TMS44409 series is commonly found in applications such as personal computers, graphics cards, and networking equipment where high-speed memory access is critical. This device is housed in a 20-lead SOJ (Small Outline J-Lead) plastic package with a 1.27mm terminal pitch, suitable for surface mounting. The technology employed is MOS, and it features 3-state output characteristics.
