    摘要: A nonvolatile memory apparatus which includes plural memories one of which is a nonvolatile memory such as a Flash EEPROM capable of being specified a plurality of operations from a processing unit of the apparatus including an erase operation, the erase operation in the nonvolatile memory performs a threshold voltage moving operation and a verify operation, and the nonvolatile memory is capable of releasing the I/O bus during the erase operation to thereby allow accessing of other memories and/or system components. For example, during this erase operation, the Flash EEPROM is able to free the I/O data terminal such that the EEPROM becomes electrically isolated from the CPU. The CPU is then able to perform data processing by the system bus where information can then be transferred/received such as between other memories, e.g., ROM and RAM, and otherwise with the I/O port.

By applying a potential to a select gate electrode SG of a memory cell having a source region MS and a drain region MD and to the source region MS and by accelerating electrons flowing in a channel through a high electric field produced between a channel end of the select transistor and an end of an n-type doped region ME disposed under the memory gate electrode MG, hot holes are generated by impact ionization, and the hot holes are injected into a silicon nitride film SIN by a negative potential applied to the memory gate electrode MG, and thereby an erase operation is performed.
