An embodiment for operation of an emulated electrically erasable (EEE) memory system includes a memory controller configured to identify a first quick record of a stack of quick records as a present record, wherein the stack of quick records are stored in a non-volatile portion of memory, the first quick record has a quick record status identifier (ID) that indicates the stack of quick records has not been qualified, determine a record status of a next record after the present record in the non-volatile portion of memory, and in response to a determination that the next record has a blank record status ID: update the next record from the blank record status ID to the quick record status ID, wherein the blank record status ID indicates that the next record is part of the stack of quick records, and qualify the present record using the plurality of program steps.

Fast write mechanism for emulated electrically erasable (EEE) system

A method of operating an emulated electrically erasable (EEE) memory system includes entering a quick write mode for a predetermined amount of time, upon detection of imminent power loss of the EEE memory system. A first write request is received immediately subsequent to entering the quick write mode, where the first write request includes a first address of an emulated memory of the EEE memory system and associated first data to be written at the first address. A first new record is created in non-volatile memory of the EEE memory system during the quick write mode, where the first new record includes the first address, the associated first data, and a blank record status identifier. The first new record is updated to have a quick record status ID, in response to a determination that record data of the first new record passes verification.
