ABSTRACT:
A method for writing data to an entry in a portion of a flash EEPROM memory array during a period in which that portion of the array is being erased and writing is prohibited. The method includes writing the data to a new entry position apart from the portion of the array which is being erased along with a revision number which is greater than the revision number of the original data in the original portion of the array, writing of the busy condition of the original entry to a temporary storage position apart from the portion of the array which is being erased, and invalidating entries listed in the temporary storage position when the erase operation is concluded.
