Abstract: According to an example, versioned memory implementation may include comparing a global memory version to a block memory version. The global memory version may correspond to a plurality of memory blocks, and the block memory version may correspond to one of the plurality of memory blocks. A subblock-bit-vector (SBV) corresponding to a plurality of subblocks of the one of the plurality of memory blocks may be evaluated. Based on the comparison and the evaluation, a determination may be made as to which level in a cell of one of the plurality of subblocks of the one of the plurality of memory blocks checkpoint data is stored.
