  • Patent number: 10395753
    Abstract: A semiconductor memory device is provided to keep data reliability while decreasing programming time. A NAND flash memory loads programming data from an external input/output terminal to a page buffer/sense circuit. A detecting circuit for monitoring the programming data detects whether the programming data is a specific bit string. If it is detected that the programming data is not a specific bit string, a transferring/writing circuit transfers the programming data kept by the page buffer/sense circuit to an error checking correction (ECC) circuit, and an ECC code generated by an ECC operation is written to the page buffer/sense circuit. If it is detected that the programming data is a specific bit string, transfer of the programming data kept by the page buffer/sense circuit is forbidden and a known ECC code corresponding to the specific bit string is written to the page buffer/sense circuit.

  • Publication number: 20190237148
    Abstract: A semiconductor memory device which is able to perform a power sequence with high reliability is provided. When a power from an external device is supplied, the controller of the flash memory of the invention is configured to read codes stored in a read-only memory in synchronization with a clock signal to perform a power-on sequence. In addition, the controller is further configured to deactivate the clock signal so as to pause the power-on sequence when it has been detected during the power-on sequence that the voltage of the power is not greater than a threshold, and to activate the clock signal to resume the power-on sequence when it is detected that the voltage of the supplied power exceeds the threshold again.

  • Publication number: 20190163401
    Abstract: The disclosure prevents inconsistencies in a busy state between a master side memory chip and a slave side memory chip during a reset operation. A flash memory device (100) of the disclosure includes a master side memory chip (200) and at least one slave side memory chip (300). A controller (230) of the master side memory chip (200) selects the master side memory chip or the slave side memory chip based on an externally inputted address, and performs a reset of the selected memory chip when a reset command is inputted. The data read from a specific area of a memory cell array of the master side memory chip is set in a register. The controller (230) controls a readout of the reset in a manner that time required for setting the data of the register is longer than time required for the reset of the selected memory chip.

  • Patent number: 10068659
    Abstract: The invention provides a semiconductor memory device capable of maintaining data reliability and shortening programming time. A flash memory of the invention includes a memory array 100, a page buffer/sensor circuit 160, an input/output buffer 110 connected to an external input/output terminal, and an ECC circuit 120 for checking and correcting data errors. In a programming operation, the input/output buffer 110 loads programming data into the page buffer/sensor circuit 160 and the ECC circuit 120 in parallel. The ECC circuit 120 writes parity bits generated from ECC calculation into a spare domain of the page buffer/sensor circuit 160. After the ECC procedure, the data held by the page buffer/sensor circuit 160 are programmed to a selected page.
