    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.
