Texas Instruments SMJ44C251 series Video DRAM, part number SMJ44C251B-10JDL, offers a 256K x 4 memory organization with a maximum access time of 100ns. This CMOS component utilizes Fast Page mode with EDO for enhanced performance. It supports RAS Only/CAS Before RAS and Hidden refresh modes, along with a 512 x 4 SAM port for specialized video memory operations. The device is housed in a 28-lead ceramic dual in-line package (CDIP) with through-hole mounting. Operating over a temperature range of 0°C to 70°C, it requires a supply voltage between 4.5V and 5.5V, typically 5V. The SMJ44C251B-10JDL is suitable for applications requiring high-speed display memory, including graphics controllers and display systems.
