Abstract: An apparatus includes a solid-state a solid-state non-volatile computer memory; and a controller coupled to the memory. The controller to: generate a data set including a tag that indicates that the data set is valid; write the data set into a block of the memory, wherein the block includes multiple addressable locations set to a common first binary value before the write; generate a subsequent data set including a tag that indicates that the subsequent data set is valid; update the tag of the written data set to indicate that the written data set is invalid, wherein the update includes setting an addressable location corresponding to the tag to second binary value different from the first binary value; write the subsequent data set to addressable locations in the block of memory other than the addressable locations of the invalid data set.

Abstract: An example computing device includes a controller to control operation of a firmware subsystem of the computing device. The controller is separate from a main processor of the computing device. A memory stores subsystem data that is useable by the controller. The subsystem data includes recovery information executable by the controller to initiate recovery of the subsystem. The computing device further includes recovery coordination instructions. The recovery coordination instructions determine integrity of the recovery information as stored on the memory and. In response to determining that the recovery information lacks integrity, the recovery coordination instructions initiate recovery of the firmware subsystem using a backup of the recovery information and perform recovery of the firmware subsystem using an update to the firmware subsystem.
