... Typical 10,000 Write Cycles Description The AT49BV004(T) and AT49BV4096A(T) are 3-volt, 4-megabit Flash Memories organized as 524,288 words of 8 bits each or 256K words of 16 bits each. Manufac- tured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 120 ns with power dissipation of just 2.7V read. When deselected, the CMOS standby current is less than 50 µ ...

When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high impedance state whenever high ...
