Publication number: 20230385224Abstract: A memory subsystem is provided, including a memory controller integrated circuit (IC), a memory bus and a memory IC, all which use fewer signals than common DDR type memory of the same peak bandwidth. Using no more than 22 switching signals, the subsystem can transfer data over 3000 Megabytes/second across the bus interconnecting the ICs. Signal count reduction is attained by time-multiplexing address/control commands onto at least some of the same signals used for data transfer. A single bus signal is used to initiate bus operation, and once in operation the single signal can transfer addressing and control information to the memory IC concurrent with data transfer via a serial protocol based on 16 bit samples of this single bus signal. Bus bandwidth can be scaled by adding additional data and data strobe IO signals. These additional data bus signals might be used only for data and data mask transport.Type: ApplicationFiled: April 21, 2023Publication date: November 30, 2023Applicant: Etron Technology, Inc.Inventor: Richard Dewitt Crisp

Publication number: 20200125506Abstract: A multi-bank Superscalar Memory IC and system for use therein is disclosed. Using multiple independent addressing ports, multiple memory locations can be accessed simultaneously leading to a higher level of concurrency than supported by common DDR type memories. One disclosed embodiment is a Memory IC with two separate Data IO Ports that can support simultaneous read and write operations to the same memory IC, leading to reduced operating power for a given realtime video processing workload by exploiting the higher level of concurrency to deserialize operations leading to a reduction in operating clock frequency.Type: ApplicationFiled: October 17, 2019Publication date: April 23, 2020Inventor: Richard Dewitt Crisp
