  • Patent number: 11211115
    Abstract: A random access memory array including a plurality of local memory group ways, each local memory group way including, a plurality of local memory groups, each local memory group including, a memory column including a plurality of memory cells, a pair of local bitlines operatively connected to the plurality of memory cells, and a local group periphery including a local bitline multiplexer operatively connected with the pairs of local bitlines of the corresponding local memory group; and a pair of global read bitlines operatively connected to outputs of the plurality of local group peripheries, a global read bitline multiplexer operatively connected to outputs of the plurality of pairs of the global read bitlines from the local memory group ways, and a bitline operational block operatively connected an output of the global read bitline multiplexer.

  • Patent number: 11094355
    Abstract: A random access memory having a memory array having a plurality of local memory groups, each local memory group including a plurality of bitcells arranged in a bitcell column, a pair of local bitlines operatively connected to the plurality of bitcells, a pair of global read bitlines, a local group read port arranged between the pair of local bitlines and the pair of global read bitlines for selectively accessing one of the local bitlines depending on a state of a selected bitcell, and a local group precharge circuit operatively arranged between the pair of local bitlines.
