FERROELECTRICS RANDOM ACCESS MEMORY DEVICE AND BURST MODE OPERATION METHOD THEREOF

摘要

A ferroelectric memory device and burst mode operation method thereof is provided to output a plate control signal disabling a plate line by including a plate control circuit. A ferroelectric memory device and burst mode operation method thereof comprises a memory cell array(30), a cell selector, and a plate control circuit(25). The memory cell array includes a plurality of word lines and a plurality of ferroelectric memory cells connected between a plate line and a bit line. The cell selector enables the word line and the plate line in response to an internal address signal and a plate control signal, and disables the word line after a predetermined time if the plate line is disabled. The plate control circuit outputs the plate control signal disabling the plate line if an external chip enable signal applied from outside is disabled.
