M29W640G: 64-Mbit (8 Mbit X8 Or 4 Mbit X16, Uniform Block Or Boot Block) 3 V Supply Flash MemoryM29W640G: 64-Mbit (8 Mbit X8 Or 4 Mbit X16, Uniform Block Or Boot Block) 3 V Supply Flash Memory,The M29W640G is a 64-Mbit (8 Mbit x8 or 4 Mbit x16) non-volatile memory that CAN be
read, erased and reprogrammed. These operations CAN be performed using a single low
voltage (2.7 to 3.6V) supply. On power-up the memory defaults to its read mode.
The memory is divided into blocks that CAN be erased independently so it is possible to
preserve valid data while old data is erased. Program and erase commands are written to
the command Interface of the memory. An on-chip program/erase controller simplifies the
process of programming or erasing the memory by taking care of all of the special
operations that are required to update the memory contents. The end of a program or erase
operation CAN be detected and any error conditions identified. The command set required to
control the memory is consistent with JEDEC standards. By Numonyx
