    摘要: Multi-level cell programming methods are provided. A method includes providing a page buffer including first and second registers connected to first and second memory cell blocks, respectively. A least significant bit (LSB) program of each memory cell is completed. Most significant bit (MSB) data is set in a first node of the first register. An MSB program is performed. When the MSB program is performed at a first verify voltage, first data at a first voltage level is set in the first node. When the MSB program is performed at a second verify voltage, second data at a second voltage level, opposite to the first voltage level, is set in the first node. When the MSB program is performed at a third verify voltage, the first data is set in the first node. The MSB program is repeated according to the first node data.

    摘要: A page buffer includes a first register, a second register and a data I/O unit. The first register temporarily stores data to be programmed into cells included in a first memory cell block group, or reads and stores data of a corresponding memory cell. The second register temporarily stores data to be programmed into cells included in a second memory cell block group, or reads and stores data of a corresponding memory cell. The data I/O unit inputs specific data to the first register and the second register, or outputs data stored in the first register and the second register.

    摘要: A page buffer includes a first latch coupled between a sensing node and a data input/output node for storing data to be programmed. The sensing node is coupled to a bit line corresponding to an MLC selected for programming. The data input/output node receives/outputs data. A second latch is coupled to the sensing node for performing a program, verifying or read operation. A first switching means is coupled between the first latch and the sensing node for transmitting data stored in the first latch to the bit line through the sensing node when the program operation is performed. A second switching means is coupled to a first node of the second latch and the sensing node for verifying a first program operation. A third switching means is coupled between a second node of the second latch and the sensing node for verifying a second program operation.
