ABSTRACT:
Various embodiments address the problem of efficiently reading data from nonvolatile memory. Nonvolatile memory circuit, method, and manufacturing method embodiments relate to a virtual ground array of nonvolatile memory cells which are read by precharging the drains of multiple nonvolatile memory cells and measuring the resulting currents. Power consumption and read margins are improved by reading multiple cells. Unnecessary bit line precharging can be avoided.
