  • Patent number: 11809706
    Abstract: A memory management method, a memory storage device, and a memory control circuit unit are provided. The method includes: reading first data from a first physical unit by using a first read voltage level according to first management information among multiple candidate management information; decoding the first data and recording first error bit information of the first data; and adjusting sorting information related to the candidate management information according to the first error bit information. The sorting information reflects a usage order of the candidate management information in a decoding operation.

  • Patent number: 9123418
    Abstract: A NAND flash memory unit is described, including a string of memory cells connected in series, S/D regions coupled to two terminals of the string, at least one select transistor couple between a terminal of the string and an S/D region, and at least one erase transistor couple between the at least one select transistor and an S/D region. The select transistor is for selecting the string of memory cells. The erase transistor is for reducing Vt-shift of the select transistor.
