Semiconductor memory device capable of adjusting a wordline voltage for a write operation
Abstract:
A semiconductor memory device includes a memory cell array including a plurality of wordlines, a plurality of bitlines and a plurality of cells; a bitline decoder configured to couple a global bitline to one of the plurality of bitlines according to a bitline selection signal; a bitline driver configured to provide bitline current to the global bitline; a wordline decoder configured to couple a global wordline to one of the plurality of wordlines according to a wordline selection signal; a wordline driver configured to provide a wordline drive voltage to the global wordline during a write operation and to adjust the wordline drive voltage according to a write address; and a write control circuit configured to generate the wordline selection signal and the bitline selection signal, and to control the bitline decoder, the wordline decoder, and the bitline driver.
