ABSTRACT:
A wordline decoder for a memory device drives a word line of a memory array and comprises a first circuit, a second circuit, and a buffer circuit. The first circuit receives voltage from a first voltage source. The second circuit receives voltage from a second voltage source. During an erase cycle, the buffer circuit receives a third voltage higher than the second voltage and lower than the first voltage. During read and program cycles, the buffer circuit receives a fourth voltage substantially equal to the first and second voltage.
