Texas Instruments SMJ4256-15FVS is a 256K x 1 bit page mode DRAM. This NMOS technology component offers a maximum access time of 150ns, supporting RAS-only, CAS-before-RAS, and hidden refresh modes. It features separate I/O and 3-state output characteristics. The device is housed in an 18-terminal ceramic chip carrier (CQCC18) with a rectangular, metal-sealed cofired package. Operating across a temperature range of -55°C to +110°C, it requires a supply voltage between 4.75V and 5.25V. The SMJ4256 series is suitable for applications requiring high-speed data access and storage, including telecommunications infrastructure and industrial control systems.
