The Texas Instruments TMX44C256 is a 1-Mbit (256K x 4) Fast Page Mode DRAM, operating with a maximum access time of 150ns. This CMOS component utilizes a 256K x 4 memory organization and supports asynchronous operation. The device features a 3-state output characteristic and is housed in a 20-lead SOJ (Small Outline J-Lead) plastic package, specifically identified by the R-PDSO-J20 JESD-30 code. With a supply voltage range of 4.5V to 5.5V, it is suitable for applications requiring reliable memory solutions in areas such as industrial control and consumer electronics. The 512 refresh cycles ensure data integrity within its operational parameters.
