An EEPROM includes an array of memory cells divided into a plurality of memory blocks in a semiconductor well region in a substrate. Each block includes series arrays of FATMOS transistors each acting as one memory cell, wherein binary information may be stored in a selected cell transistor by...
The memory cells of the Flash EEPROM are partitioned into a plurality of sectors that individually are erasable together as a unit. The individual sectors are provided with a user data portion and an overhead portion which allow for operations similar to that of a magnetic disk drive. In one...
