The GM71C(S)4400C/CL 1,048,576 WORDS x 4BIT CMOS DYNAMIC RAM is a new type of dynamic random access memory launched by Samsung Electronics. It uses advanced CMOS process technology and has higher density, higher performance and various functions. This product uses fast page mode as a high-speed access mode, and provides multiplexed address inputs, which can be used in standard 300mil 20(26) pin plastic SOJ and standard 300mil 20(26) pin plastic TSOP II packages. The package size provides higher system bit density and is compatible with widely available automated testing and insertion equipment. The product also has a single power supply (5V+/-10%), and can be directly interfaced with high-performance logic families such as Schottky TTL.
The GM71C(S)4400C/CL is a 1,048,576‑word by 4‑bit CMOS dynamic RAM offered by LG Semicon. It features a single 5 V supply, fast page mode operation, and TTL‑compatible I/O.
The document provides detailed electrical characteristics, timing parameters, package dimensions, and ordering information for the 60 ns, 70 ns, and 80 ns access‑time versions in both SOJ and TSOP II packages.
