Embodiment Construction

[0042] Embodiments of the invention are generally directed to improving serial port memory communication latency and reliability; however, they are equally applicable to other types of interfaces, such as high speed parallel interfaces.

[0043] As used herein, "memory" refers to computer systems (such as Figure 2D , 2E ) responsible for retrieving previously stored data for use by any "host" (such as a computing processor) or peripheral (such as a keyboard, display, camera, mass storage (disk, optical disk, tape, etc.), network controller, or wireless network) Components used. Typically, the memory is coupled to one or more microprocessors for processing data in the computer system. Data can be stored by the host in memory such as random access memory (RAM), static RAM (SRAM), dynamic RAM (DRAM), flash memory, PROM (programmable read-only memory), erasable PROM (EPROM), electronic Erasable PROM (EEPROM), or predetermined, as is the case for Read Only Memory (ROM). The me...

Abstract

A method, apparatus and system for reducing memory latency is disclosed. In one embodiment, data between a host computer system and a memory is communicated via a port or a group of ports at the memory over multiple time intervals, wherein the host computer is coupled to the memory. Further, a command associated with the data is communicated between the host computer system and the memory via the port or the group of ports over a single time interval.

Description

[0001] This application is PCT International Application No. PCT / US2009 / 062231, International Application Date is October 27, 2009, China National Application No. 200980143643.9, entitled "Methods for Improving Serial Port Memory Communication Latency and Reliability" and system" application. [0002] related application [0003] This application is a non-provisional application of, and claims priority to, US Provisional Application No. 61 / 109,480, filed October 29, 2008. technical field [0004] Embodiments of the invention relate generally to the field of computer memory, and in particular, to improving serial port memory communication latency and reliability. Background technique [0005] In memory systems using high-speed serial interfaces, where commands and data are communicated between a host or hosts and the memory via various ports, it is desirable to provide maximum bandwidth in combination with some error detection to ensure proper system operation. [0006] Ser...
