USAGE OF AN SDRAM AS STORAGE FOR CORRECTION AND TRACK BUFFERING IN FRONTEND ICS OF OPTICAL RECORDING OR REPRODUCTION DEVICES

摘要

A method and arrangement for using Synchronous Dynamic Random Access Memory (SDRAM) as storage for correction and track buffering in front end ICs of optical recording or reproduction devices. Data to be stored or read is organized in appropriate bursts for accelerating the SDRAM (SDR) traffic. The SDRAM is built around two banks of memory, and are accessed using a pipelined address logic, thereby accelerating access speeds.
