    摘要: A nonvolatile semiconductor memory device is provided which includes a memory array, a page buffer, and a row decoder. The memory array includes a plurality of nonvolatile memory cells, a bit line, and a word line, and the row decoder driven to control the word line of the memory array. The page buffer is electrically connected to the bit line and includes a main data latch and a sub-data latch. The page buffer, which is configured such that flipping of the main data latch is inhibited according to a logic state of the sub-data latch, further includes a main latch block, a sub-latch block, and a latch control block. The main latch block drives the main data latch and maps a logic state of the main data latch to a threshold voltage of a corresponding memory cell through the bit line. The sub-latch block drives the sub-data latch, where the sub-data latch is flipped depending on the voltage level of the bit line. The latch control block selectively flips the main data latch depending on the voltage level of the bit line, where the latch control block is disabled depending on a logic state of the sub-data latch.

    摘要: According to one aspect, a memory cell array includes a bit line connected to a plurality of nonvolatile memory cells, where the nonvolatile memory cells are selectively programmable in any one of at least first, second, third and fourth threshold voltage states, and where the first, second, third and fourth threshold voltage states correspond to four different data values defined by first and second bits. A page buffer circuit stores a logic value as main latch data and is responsive to a main latch signal to selectively flip the logic value of the main latch data according to a voltage level of the bit line. A sub-latch circuit stores a logic value as sub-latch data and is responsive to a sub-latch signal to selectively flip the logic value of the sub-latch data according to the voltage level of the bit line. The memory device is operable in a read mode which reads the threshold voltage state of the non-volatile memory cells and a programming mode which programs the threshold voltage state of the non-volatile memory cells, wherein the page buffer circuit is selectively responsive to the sub-latch data to inhibit flipping of the logic value of the main latch data in the programming mode.
