Texas Instruments SMJ44C250 Series Video DRAM, part number SMJ44C250-10HJM, is a 1048576-bit CMOS memory device organized as 256K words by 4 bits. This asynchronous DRAM offers a maximum access time of 100ns and operates from a 5V supply voltage. It supports Fast Page Mode access, along with RAS Only, CAS Before RAS, and Hidden Refresh modes for efficient memory operation. The device features two ports and a 3-state output characteristic. Packaged in a 28-lead ceramic, metal-sealed cofired SOJ (Small Outline J-Lead) with a terminal pitch of 1.27mm, it is designed for surface mounting. Operating across an industrial temperature range of -55°C to +125°C, the SMJ44C250-10HJM is suitable for applications in graphics controllers, high-resolution displays, and other video-intensive systems.
