Introduction
James E. Ponder is a notable inventor based in Cat Spring, Texas. He has made significant contributions to the field of semiconductor technology, holding a total of six patents. His work primarily focuses on advancements in CMOS integrated circuits and memory cell designs.
Latest Patents
One of his latest patents is for a CMOS integrated circuit device. This invention provides an improved CMOS device and method of making it, utilizing a standard N-channel self-aligned silicon gate structure modified to include a P-channel transistor. A P-type substrate serves as the starting material, with an N-type tank formed for the P-channel transistor. Field oxide is grown after the N-type tank is formed, and a polycrystalline silicon layer is deposited and patterned to create gates for both N- and P-channel transistors. The sources and drains for the two types of transistors are formed through separately masked P- and N-type diffusions or implants.
Another significant patent involves a semiconductor memory cell with a clocked voltage supply from data lines. This MOS memory cell of the static type employs a pair of cross-coupled driver transistors forming a bistable circuit. Load resistors are replaced by a pair of series coupling transistors that connect storage nodes to complementary precharged data lines. The coupling transistors are turned on in sequence for refresh, allowing an intermediate node to be charged during a first phase and discharged into the storage nodes during the second phase. Both transistors are activated simultaneously for read or write operations.
