The Texas Instruments SMJ44C256-12FQMT is a 256K x 4-bit Fast Page Mode Dynamic Random Access Memory (DRAM) device. Featuring a 120ns maximum access time, this MOS technology component utilizes the CAS-before-RAS refresh mechanism for efficient operation. The memory organization is 256K words by 4 bits, providing a total density of 1048576 bits. This device is housed in a 20-terminal ceramic, metal-sealed cofired small outline package (JESD30 Code: R-CDSO-N20) suitable for surface mounting, with a terminal pitch of 1.27mm. Operating from a supply voltage range of 4.5V to 5.5V, it supports an asynchronous operating mode. The SMJ44C256 series components are designed for demanding applications, including military and aerospace systems, where high reliability and performance are critical.
