Abstract

A memory includes a bit cell array including a plurality of word lines and address decode circuitry having an output to provide a predecode value. The address decode circuitry includes a first plurality of transistors having a first gate oxide thickness. The memory further includes word line driver circuitry having an input coupled to the output of the address decode circuitry and a plurality of outputs, each output coupled to a corresponding word line of the plurality of word lines. The word line driver includes a second plurality of transistors having a second gate oxide thickness greater than the first gate oxide thickness. A method of operating the memory also is provided.
