Short stripe repair in memory systems

Abstract

Aspects of the present disclosure configure a memory sub-system controller to provide adaptive repair on short stripes. The memory controller groups a plurality of sets of blocks of a set of memory components into respective block stripes. The memory controller computes an average width across the block stripes, the average width representing an average quantity of blocks within each of the block stripes that is associated with a reliability grade that transgresses a threshold and determines that a first block stripe of the block stripes includes a lesser quantity of blocks, associated with reliability grades that transgress the threshold, than the average quantity of blocks. The memory controller, in response to determining that the first block stripe includes the fewer quantity of blocks than the average quantity of blocks, associates one or more blocks of a second block stripe of the block stripes with the first block stripe.
