Low complexity crosstalk mitigation in a nonvolatile memory

Abstract

A storage system includes circuitry and multiple memory cells. The memory cells are arranged in multiple Word Lines (WLs), including a target WL. The circuitry includes combinational logic implemented in hardware, the circuitry configured to: read a page from a group of target memory cells in the target WL multiple times to produce multiple respective target binary readouts, read a group of neighbor memory cells in a WL neighboring to the target WL so as to produce a single neighbor binary readout, apply the combinational logic to both the target binary readouts and the neighbor binary readout to produce (i) output bits of the page, and (ii) respective binary confidence levels associated with the output bits, and transmit the output bits and the binary confidence levels to a controller.
