MT4C4004

The MT4C4004 is designed as a randomly accessed solid-state memory containing 4,194,304 bits organized in a x4 configuration. This 1Meg x4 DRAM is unique in that each CAS controls its corresponding data i/O port in conjunction with OE.

MT4C4004 has ten features. (1)Four independent CAS controls, allowing individual manipulation to each of the four data input/output ports. (2)Offers a single chip solution to byte level parity for 36-bit words when using 1Meg x4 DRAMs for memory. (3)Emulates write-per-bit, at design-in level, with simplified timng constraints. (4)High performance CMOS silicon gate process. (5)Single +5V+/-10% power supply. (6)Low power, 3mW standby 225mW active typical. (7)All inputs outputs and clocks are fully TTL and CMOS compatible. (8)1024-cycle refresh in 16ms. (9)Refresh modes RAS-ONLY, CAS-before-RAS and HIDDEN. (10)CAS before RAS cycles with WE as a don't care. Those are all the main features.

Some absolute maximum ratings of MT4C4004 have been concluded into several points as follow. (1)Its voltage on Vcc relative to Vss would be from -1V to 7V. (2)Its storage temperature range ceramic would be from -65°C to 150°C. (3)Its storage temperature plastic range would be from -55°C to 150°C. (4)Its power dissipation would be 1W. (5)Its sort circuit output current would be 50mA. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of MT4C4004 are concluded as follow. (1)Its supply voltage would be min 4.5V and max 5.5V. (2)Its input high voltage all inputs logic 1 would be min 2.4V and max Vcc+1V. (3)Its input low voltage all inputs logic 0 would be min -1.0V and max 0.8V. (4)Its input leakage current would be min -2uA and max 2uA. (5)Its output leakage current would be min -10uA and max 10uA. (6)Its output levels would be min 2.4V for high level and would be max 0.4V for low level. And so on.
