摘要:
A data storage includes a memory array including a plurality of memory cells, and peripheral circuitry disposed underneath the memory array. The peripheral circuitry includes an M-tier sense amplifier (SA) circuit including X stacks of SA latches, wherein each SA latch is respectively coupled to a bit line of a memory cell of the plurality of memory cells; and an N-tier memory cache data (XDL) circuit including Y stacks of XDL latches, wherein M is less than N, and X is greater than Y. The peripheral circuitry further includes data path circuitry coupling (i) each SA latch of the X stacks of SA latches to (ii) a respective XDL latch of the Y stacks of XDL latches.
