Abstract
Disclosed is a page buffer for a nonvolatile semiconductor memory device and a related method of operation. The page buffer includes a unidirectional driver between a loading latch unit used for storing a data bit in the page buffer and a bitline used to program a memory cell connected to the page buffer.
Claims11
A page buffer for a nonvolatile semiconductor memory device, the page buffer comprising:
- a loading latch unit adapted to load and store a data bit in a latch node;
- and,
- a unidirectional driver adapted to receive the data bit from the loading latch unit and drive a corresponding write data bit onto a bitline connected to a memory cell.
A page buffer for a nonvolatile semiconductor memory device, the page buffer comprising:
- a loading latch unit loading and storing a data bit in a latch node;
- a unidirectional driver receiving the data bit from the latch node and driving a corresponding write data bit onto a bitline by way of a sensing node, wherein the bitline is connected to a memory cell;
- a sensing detector flipping a logic state of the data bit stored in the latch node relative to a logic state of a data bit apparent at the sensing node;
- and,
- a buffer selection unit receiving the write data bit from the unilateral driver and sending the write data bit to the bitline by way of the sensing node in response to a buffer selection signal.
