Abstract
A nonvolatile memory includes five transistors. The memory has an MOS transistor in series with two pairs of transistors, where each pair includes a floating gate transistor and a metal-oxide-semiconductor transistor electrically connected in parallel. The memory structure may be formed with three levels of silicon-containing or metal-containing layers. The memory structure is less susceptible to read disturb errors compared to a prior art dual-bit nonvolatile memory structure.
