An integrated circuit having a plurality of sectors is disclosed. One embodiment includes a sector driver for simultaneously driving word lines corresponding to a single sector, the sector driver being connected to each word line and comprising a programmable sector memory for storing the sectors and word lines corresponding to each sector.

Integrated circuit having a word line driver

This invention provides a semiconductor memory device and a corresponding method of operation. The semiconductor memory device comprises a semiconductor substrate having a first conductivity; a plurality of gate structures for storing charge in a non-volatile manner regularly arranged in above the surface of the semiconductor substrate and electrically isolated therefrom; a plurality of wordlines, each of the gate structures being connected to one of the wordlines and a group of the gate structures being connected to a common wordline; and a plurality of active regions, each of the active regions being individually connectable to at least one of the gate structures.

Charge coupled EEPROM device and corresponding method of operation

A semiconductor memory device includes a semiconductor substrate having a first conductivity type and multiple parallel trenches extending in a first direction in the substrate. Each trench is filled with an isolation material and has an adjacent trench separated therefrom by a strip region. The device also includes multiple gate structures, for storing charge in a nonvolatile manner, arranged above the surface of the substrate and electrically isolated therefrom. The gate structures are arranged in parallel strips extending in a second direction that cross the strip regions. The device further includes multiple word lines, each of which is arranged on a corresponding gate structure from the multiple gate structures. The device also includes multiple active regions of a second conductivity type, each of which is arranged at one end of a corresponding strip region and each of which is electrically connectable to the gate structures of the corresponding strip region.
