The Texas Instruments TMS44C256-80DN is a 1-Mbit Fast Page Mode DRAM with a memory organization of 256K words by 4 bits. This CMOS component offers an access time of 80 ns from Row Address Strobe (RAS) to Column Address Strobe (CAS) and supports various refresh modes including RAS-only, CAS-before-RAS, and hidden refresh with 512 refresh cycles. It operates asynchronously with a supply voltage range of 4.5V to 5.5V and features 3-state outputs. The TMS44C256-80DN is housed in a 20-lead Small Outline J-Lead (SOJ) package, suitable for surface mounting, and finds application in computing, telecommunications, and industrial control systems.
