GENERATING VIRTUAL BLOCKS USING PARTIAL GOOD BLOCKS
This abstract first appeared for US patent application 20240256444 titled 'GENERATING VIRTUAL BLOCKS USING PARTIAL GOOD BLOCKS
Original Abstract Submitted
aspects of the present disclosure configure a system component, such as a memory sub-system controller, to generate virtual or superblocks using multiple partial good blocks. the controller identifies a first partial good block (pgb) in a set of memory components, the first pgb having first subset of word line groups (wgrs) that are categorized as being non-defective. the controller searches for a second pgb in the set of memory components having a second subset of wgrs that are categorized as being non-defective. the controller computes a total quantity of wgrs based on the first quantity of wgrs in the first subset of wgrs and a second quantity of wgrs in the second subset of wgrs and, in response, combines the first pgb and the second pgb to form an individual virtual block.
