Patent number: 12380955Abstract: 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.Type: GrantFiled: January 6, 2023Date of Patent: August 5, 2025Assignee: WINDBOND ELECTRONICS CORP.Inventor: Chung-Meng Huang

Patent number: 8462554Abstract: 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.Type: GrantFiled: March 3, 2011Date of Patent: June 11, 2013Assignee: Winbond Electronics Corp.Inventors: Chung-Meng Huang, Im-Cheol Ha
