Abstract:
Systems and methods for detecting a command execution abort are disclosed. Power failure may abort the writing of data in a memory device prematurely, resulting in potential data corruption. A memory device controller in the memory device sends commands, such as write or erase commands, to one or more memory integrated circuit chips. Along with executing the commands, the memory integrated circuit chips track execution of the commands by storing the address at which the command is being executed along with flag(s) indicative of the progress executing the command (e.g., command has begun and/or completed execution). When a power failure occurs, the memory device controller may poll the memory integrated circuit chips for the address/flags information to determine whether (or where) the command abort occurred. Thus, relying on the address/flag(s), the memory device controller may more quickly or easily determine whether a command abort has occurred.
