DATA OUTPUT DRIVING CIRCUIT FOR FLASH MEMORY DEVICE

摘要

PURPOSE: A data output driving circuit is provided to transfer data of a stable level to a data pin regardless of delay of state data when a flash memory device performs a read operation. CONSTITUTION: A flash memory device performs a state reading operation so that an operation performed inside a chip of the flash memory device may be known to outside. The flash memory device includes data pins(DQ) for informing outside of an operation state performed inside the chip during the state reading operation and a data output driving circuit(140) for outputting state data to the data pins. The data output driving circuit has a state data generator(141-145,TG1,TG2) and a driver(PM1,NM1). The state data generator outputs state data in synchronization with a rising edge of an internal output enable signal synchronous to an external output enable signal when a signal informing of the state reading operation becomes active. The driver receives the state data and outputs the state data whenever the external output enable signal toggles in a low level in response to the state reading enable signal.
