M29W004B - 4 Mbit 512Kb x8 / Boot Block Low Voltage Single Supply Flash Memory
The M29W004 is a non-volatile memory that may be erased electrically at the block or chip level and programmed in-system on a Byte-by-Byte basis using only a single 2.7V to 3.6V VCC supply.
For Program and Erase operations the necessary high voltages are generated internally.
