Abstract

Memory control device, method for changing memory addresses, and memory system. A memory control device detects memory accesses and communicates with a plurality of memory modules that are serially connected. The memory control device changes the allocation of addresses for the plurality of memory modules in accordance with the detection of memory accesses in the detection step.

Description

technical field [0001] The invention relates to an access control device, a method for changing memory addresses and a storage system. Background technique [0002] With recent advances in semiconductor technology, the internal operating frequency of processors and LSIs has been significantly increased. It is also necessary to increase the operating frequency of a memory externally connected to the LSI, especially a main memory using a DRAM, and in recent years speeding up of the memory module is progressing. [0003] In this case, it is necessary to change the structure and configuration of memory modules using DRAMs in response to this increase in speed. Traditionally, for PC 133 (SDRAM operating at 133MHz clock frequency and the standard for DIMMs plugged into this SDRAM) memory modules etc., in an unbuffered configuration (a configuration that does not connect (use) a buffer chip), even as-is There is also no problem in distributing the signals of both commands and dat...
