Checkpointing for DRAM-less SSD
Abstract:
Methods and apparatus related to checkpointing for Solid State Drives (SSDs) that include no DRAM (Dynamic Random Access Memory) are described. In one embodiment, Non-Volatile Memory (NVM) stores an original Logical address to Physical address (L2P) table entry and a shadow L2P table entry. Allocation logic circuitry causes storage of the original L2P table entry and the shadow L2P table entry sequentially in the NVM. Data read from the shadow L2P table entry is capable to indicate a state of the original L2P table entry. Other embodiments are also disclosed and claimed.
