Patent ID: 8654591

Claim:
A local word line driver for driving a local word line in a sector of a memory array of an NOR flash memory, the local word line driver having two transistors, comprising only a first transistor and a second transistor connected in series with each other, wherein: the first transistor is an NMOS transistor having a gate terminal for receiving a first control signal of a global word line decoder, a drain terminal coupled to a drain control terminal for receiving a drain control signal, and a source terminal coupled to the local word line; and the second transistor is an NMOS transistor having a gate for receiving a second control signal of a global word line decoder, a drain terminal coupled to a source terminal of the first transistor and coupled to the local word line, and a source terminal coupled to a source control terminal for receiving a source control signal; further wherein in the memory array of the NOR flash memory, each local word line driver is on the same column shares the drain control terminal.
