Patent ID: 7162551

Claim:
A method of operating a memory management system adapted to process linked list data files received by a packet router; said memory management system comprises a plurality of low storage capacity high speed memories and a lower speed high storage capacity bulk memory, said high speed memories have a first data rate, said bulk memory has a second data rate lower than said first data rate, said system further comprises an access flow regulator for generating requests received from said packet router for the reading and writing of linked list data files by said memories, said access flow regulator defines an interface between said packet router and said memory management system, said method comprises the steps of: initiating the writing of a linked list in said high speed memories by transmitting a write request from said access flow regulator to said high speed memories; writing a head buffer and a tail buffer and at least one intermediate buffer of said linked list into said high speed memories; and transferring said at least one intermediate buffer from said high speed memories to said bulk memory while leaving the head buffer and the tail buffer in said high speed memories.
