Abstract:
The page buffer of a nonvolatile memory device utilizing a double verification method using first and second verification voltages when performing a program verification operation includes a first latch unit including a first latch configured to store input data and results of a program operation and a first verification operation using the first verification voltage, and a second latch unit including a second latch configured to have a higher latch trip point than the first latch and to store a result of a second verification operation using the second verification voltage, which is less than the first verification voltage, when the first verification operation is performed.
Abstract:
A non-volatile memory device includes an input/output terminal mixing section configured to couple data input/output terminals of the memory device to data input/output terminals of a page buffer in accordance with a user selection. A user data authenticating section is configured to transmit a control signal to the input/output terminal mixing section so that the input/output terminal mixing section couples the data input/output terminals of the memory device to the data input/output terminals of the page buffer in accordance with the user selection. A spare cell is configured to store the coupling configuration of the data input/output terminals of the memory device and the data input/output terminals of the page buffer in accordance with the user selection.
