摘要:
Integrated circuit systems include a non-volatile memory device (e.g, flash EEPROM device) and a memory processing circuit. The memory processing circuit is electrically coupled to the non-volatile memory device. The memory processing circuit is configured to reallocate addressable space within the non-volatile memory device. This reallocation is performed by increasing a number of physical addresses within the non-volatile memory device that are reserved as redundant memory addresses, in response to a capacity adjust command received by the memory processing circuit.

A non-volatile memory may include a plurality of map blocks for storing a plurality of map units, the map units representing mapping information between physical addresses and logical addresses. A storage device may include such a non-volatile memory. A method of mapping such a non-volatile memory may include writing historical information regarding locations of valid map units among the map units included in map blocks previously allocated among the map blocks when a new map block among the map blocks is allocated, the valid map units representing valid mapping information, and constructing a map table including all of the valid mapping information based on the historical information and a result of searching a map block recently allocated among the map blocks.

A method of providing block state information in a semiconductor memory device including a flash memory comprises storing block state information on at least one bad block of the flash memory and a plurality of reserved blocks which replace the at least one bad block, and providing the stored block state information to a user in response to a command provided by the user.
摘要:
Methods of operating a non-volatile memory device that includes a first data block that stores first data and a first log block that stores an updated version of at least some of the first data is provided in which valid portions of the first data in the first data block are copied to a free block that has no data to generate a second data block. The updated version of at least some of the first data from the first log block is copied to the second data block. The first log block is designated as a reusable log block without erasing the data therefrom in response to at least one predetermined condition being satisfied.
