  • Patent number: 12380955
    Abstract: A memory controller for controlling a flash memory is provided. The memory controller includes a control circuit and a voltage generator. The control circuit is configured to program one or more pages of the flash memory in sequence, wherein each page includes a plurality of bytes. The voltage generator is configured to adjust the output voltage according to the control signal from the control circuit. The control circuit performs a programming verification operation on each byte of a current page of the one or more pages in a page programming mode, and calculates the first number of bytes which fail the programming verification operation and performs a programming operation again. The control circuit determines the programming mode of the page after the current page as the page programming mode or the byte programming mode according to the first number.

  • Patent number: 11183244
    Abstract: A memory device includes a memory array and a frequency-to-voltage converter. The memory array includes a plurality of memory cells arranged in rows and columns, and gates of the memory cells in the same row are coupled to each other and connected to a word line. The frequency-to-voltage converter coupled between the word line and a clock signal source outside the memory device receives a clock signal, and correspondingly outputs different voltages to the word line in accordance with the frequency of the clock signal.

  • Patent number: 10802962
    Abstract: A memory device and a control method for a non-volatile memory are provided. The non-volatile memory includes a target erasing region and an unselected region. The control method includes: erasing a target memory cell in the target erasing region. The unselected region is a region, excluding the target erasing region, in the non-volatile memory. The step of erasing the target memory cell includes an erasing operation, a verification operation, and an erasing loop after failing to pass the verification operation. The number of times of performing the erasing loop is an integer greater than or equal to 0. The control method further includes: refreshing a pre-defined portion in the unselected region, wherein a capacity of the pre-defined portion is determined by the number of times of performing the erasing loop.

  • Patent number: 8462554
    Abstract: Over-erase verification and repair methods for a flash memory. The flash memory is an NOR type stack flash. The disclosed method performs an over-erased column verification test on a sector of the NOR type stack flash column by column. An over-erased column repair process is individually performed on the columns which do not pass the over-erased column verification test. For the columns processed by the over-erased column repair process but still incapable of passing the over-erased column verification test, an over-erased bit verification test is performed on each bit thereof. The bits incapable of passing the over-erased bit verification test are further processed by an over-erased repair process individually.

  • Patent number: 7369441
    Abstract: A sensing circuit for multi-level flash memory is disclosed. The advantages of the sensing circuit are reducing the circuit size, reducing the testing time for tuning reference voltage and maintaining a constant difference between two approximate reference voltages. The sensing circuit comprises a reference voltage generator which includes a number of serial connected resistive devices and provides several reference voltages by voltage division; a data saving circuit outputs a data voltage; a comparing circuit compares the data voltage with the several reference voltages to output a comparing signal; a decoder receives and then decodes the comparing signal to output the data.
