摘要
The disclosure describes a scheme for managing the operations of a flash memory. The scheme enables the flash memory to be used in a write-once mode to allow non-volatile storage of small amounts of data that must be written repeatedly. Among other things, the scheme eliminates the need to erase sectors of the flash memory, thus eliminating the high current consumption associated with erasures, while enabling preservation of relevant data in those sectors. In the context of an implantable medical device, this scheme is used to store data that is needed after a reset of the device, such as MRI-related data that is/are dynamically adjusted by firmware, or program code updates.
