Lockwood's latest patents include innovations in high-speed nonvolatile memory cells. One of his notable inventions is the circuit and structure of a direct write differential nonvolatile memory cell. This memory cell features high-speed read sensing capabilities, the ability to write data without a prior erase operation, and is characterized by single polysilicon fabrication. Notably, the structural and functional symmetry it presents maximizes cell density while providing complementary differential operation. The cell utilizes a pair of cross-coupled, capacitively complementary, centrally disposed floating gate electrodes, enhancing its performance and versatility.
In another patent, Lockwood introduced a floating gate type nonvolatile memory cell, known as electrically erasable programmable read-only memories (EEPROM). This invention operates in a direct write mode and is distinguished by its absence of read disturbances. The floating gate is divided into three zones, each configured to optimize charge transfer and retention. In this design, writing data is achieved by voltage division among capacitors, while reading is conducted by detecting the conductive state of a sense transistor.
