Title: Dechang Sun: Innovator in Memory Architecture
Introduction
Dechang Sun is a notable inventor based in Eden Prairie, MN (US), recognized for his contributions to memory architecture. He holds a total of 5 patents, showcasing his expertise in the field of read-only memory (ROM) technologies. His innovative designs have significantly advanced the efficiency and functionality of memory systems.
Latest Patents
One of his latest patents is focused on a read-only memory (ROM) architecture with selective encoding. This invention provides improved memory bitcells, memory arrays, and memory architectures. In this embodiment, a memory array consists of multiple memory cells designed to store data bits. Each memory cell includes a transistor with drain, source, and gate terminals, along with several program nodes charged to a predetermined voltage and linked to respective bit lines. For a subset of these memory cells, none of the program nodes connect to the drain terminal of the transistor, allowing the memory cells to store at least one data bit, which is most frequently occurring among the data bits.
Another significant patent by Dechang Sun is the read-only memory array architecture and methods of operation. This invention describes an encoded ROM array structure that connects a first set of bitlines to a second set through a transistor when the wordline linked to the gate terminal of that transistor is activated. This encoded arrangement can be scaled to accommodate various numbers of encoded bitlines, such as 2, 4, 8, 16, and more. The first and second sets of bit lines are connected to circuits for charging and discharging the bitlines, facilitating data reading between the two sets.
