Page buffer of a flash memory
A page buffer for a flash memory has a power supply, a latch circuit, and a plurality of switches. Initially the switches are controlled for resetting a first terminal and a second terminal of the latch circuit to a respective predetermined voltage. If a memory cell is not to be programmed, the voltage levels of the first terminal and the second terminal remain unchanged when the power supply outputs a programming voltage. If the memory cell is to be programmed, the voltage levels of the first terminal and the second terminal are changed when the power supply outputs the programming voltage. Each of the first terminal and the second terminal will regain the predetermined voltage after the memory cell is completely programmed to store a predetermined binary digit.
