Abstract
This application is directed to managing errors on a memory device. The memory device includes non-volatile memory (NVM) storing data and dynamic random-access memory (DRAM) storing a logic-to-physical (L2P) table and a poison table. The memory device obtains a data access request to access a data item stored in the NVM, and the data access request includes a logical address of the data item. The memory device identifies, in the L2P table, a mapping entry corresponding to the logical address of the data item, and the mapping entry maps the logical address of the data item to a physical address of the data item within the NVM, and determines that the mapping entry has an uncorrectable error. In accordance with a determination that the mapping entry has the uncorrectable error, the memory device adds, in the poison table, an index identifying the mapping entry in the L2P table.
