Abstract

A memory device and method for performing a write-abort-safe firmware update are disclosed. In one embodiment, a location in a memory of a memory device for a firmware update is allocated. The firmware update is written into the allocated location in the memory. A pointer is written to the firmware update in a directory, and a pointer is written to the directory in a location in the memory that is read during boot-up. In another embodiment, a block in a memory of a memory device is allocated for updated file system data comprising a firmware update and a directory. The updated file system data is written into the allocated location in the memory. A pointer is written to the firmware update in the directory, and a pointer is written to the updated file system data in a boot block in the memory, wherein the boot block is read during boot-up.
