Programming an embedded flash storage device

A non-transitory computer readable medium that includes instructions to be executed by a computerized system and include instructions for performing the steps of:

• sending, by a flash memory controller, a data unit and recovery metadata to an embedded flash storage device, wherein the recovery metadata is associated with a logical address of the data unit;
• instructing the embedded flash storage device to initiate a write transaction;
• performing stages of the write transaction and stages of a management process in parallel;
• wherein the stages of the write transaction comprise:
• performing, by the embedded flash storage device, the data unit and the recovery metadata to a flash memory unit of the embedded flash storage device;
• informing, by the embedded flash storage device, the flash memory controller that the programming of the data unit and the recovery metadata succeeded;
• and
• sending, by the flash memory controller, to a host computer a transaction completion indication in response to a successful completion of the write transaction;
• and
• wherein the stages of the management process comprise:
• updating, by the flash memory controller, a flash memory unit management data structure to reflect one or more of the recovery metadata and a physical address of the flash memory unit of the embedded flash storage device;
• and
• programming, by the embedded flash storage device, the flash memory management data structure to the flash memory unit of the embedded flash storage device;
• and
• comparing, by the flash memory controller, a content of the flash memory unit management data structure with a combination of the recovery metadata and the physical address of the flash memory unit.

An embedded flash storage device comprising:

• a flash memory controller, the flash memory controller operable to:
• send, by the flash memory controller, send a data unit and recovery metadata to the embedded flash storage device, wherein the recovery metadata is associated with a logical address of the data unit;
• instruct the embedded flash storage device to initiate a write transaction;
• perform stages of the write transaction and stages of a management process in parallel;
• wherein the stages of the write transaction comprise:
• programming by the embedded flash storage device, the data unit and the recovery metadata to a flash memory unit of the embedded flash storage device;
• informing, by the embedded flash storage device, the flash memory controller that the programming of the data unit and the recovery metadata succeeded;
• and
• sending, by the flash memory controller, to a host computer a transaction completion indication in response to a successful completion of the write transaction;
• and
• wherein the stages of the management process comprise:
• updating, by the flash memory controller, a flash memory unit management data structure to reflect one or more of the recovery metadata and a physical address of the flash memory unit of the embedded flash storage device;
• and
• programming, by the embedded flash storage device, the flash memory unit management data structure to the flash memory unit of the embedded flash storage device;
• and
• compare a content of the flash memory unit management data structure with a combination of the recovery metadata and the physical address of the flash memory unit.
