  • Error write protection circuit used in semiconductor memory device
    Patent number: 6366512
    Abstract: In the present invention a bit line precharge circuit is used to prevent errors from a write operation in memory cells adjacent to the column being written. The precharge circuits are enabled by write enable and selected by the Y decoder in such a way that only precharge circuits on bit lines adjacent to the active bit lines in a write operation are activated. All other precharge circuits on bit lines more remote than immediately adjacent bit lines are not activated and thus saving power during a write operation.
