GENERAL DESCRIPTION
The device is a 64Mx16bit with spare 2Mx16bit capacity (or 128Mx8bit with spare 4Mx8bit capacity). The device is offered in 1.8V VCC Power Supply. Its NAND cell provides the most cost-effective solution for the solid state mass storage market. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased.
