    摘要: A sense amplifier circuit for a flash memory device of the present invention includes first and second pre-charge circuits for pre-charging a data line (or bit line connected electrically to the data line). The first and second pre-charge circuits are each connected to the data line. The first pre-charge circuit provides a current changed by a fluctuation of the data line voltage to the data line, and the second pre-charge circuit provides a constant voltage regardless of the fluctuation of the data line voltage to the data line. The sense amplifier minimizes the time required to pre-charge the data line (or bit line) to a desired voltage.

    摘要: Methods of operating a charge trap nonvolatile memory device include operations to erase a first string of nonvolatile memory cells by selectively erasing even-numbered nonvolatile memory cells in the first string and then selectively erasing the odd-numbered nonvolatile memory cells in the first string, which may be interleaved with the even-numbered nonvolatile memory cells. This operation to selectively erase the even-numbered nonvolatile memory cells may include erasing the even-numbered nonvolatile memory cells while simultaneously biasing the odd-numbered nonvolatile memory cells in a blocking condition that inhibits erasure of the odd-numbered nonvolatile memory cells. The operation to selectively erase the odd-numbered nonvolatile memory cells may include erasing the odd-numbered nonvolatile memory cells while simultaneously biasing the even-numbered nonvolatile memory cells in a blocking condition that inhibits erasure of the even-numbered nonvolatile memory cells.

    摘要: A flash memory and a program method of the flash memory include applying a pass voltage to word lines to boost a channel voltage, which is discharged to a ground voltage. A program voltage is applied to a selected word line and a local voltage is applied to at least one word line supplied with the pass voltage while the program voltage is being applied to the selected word line. The local voltage is lower than the pass voltage and equal to or higher than the ground voltage. The boosted channel voltage may be discharged before the program voltage is applied to the selected word line.

    摘要: In a NOR flash memory device with a serial sensing operation, and method of sensing data bits in a NOR flash memory device, the device includes a multilevel cell, a sense amplifying circuit, a data buffer, a data latch circuit, and a control logic circuit. The sense amplifying circuit serially detects plural data bits stored in the multilevel cell. The data buffer is provided to buffer the data bit detected by the sense amplifier. The data latch circuit stores an output value of the data buffer for a time. The control logic circuit regulates the sense amplifying circuit to detect a lower data bit stored in the multilevel cell in response to a higher data bit held in the data latch. Here, the control logic circuit initializes an output terminal of the data buffer before or while sensing each of the plural data bits by the sense amplifier. According to the invention, a stabilized serial sensing operation can be conducted because the data line is conditioned to a uniform charge level regardless of the level of the data bit previously sensed.
