Abstract
A memory control method includes writing converted data which is produced by carrying out a code conversion on original data into a memory. An amount of 1s in the converted data is less than an amount of 1s in the original data. Further, the memory control method includes outputting reproduced data which is provided by carrying out an inverse transformation of the code conversion on the converted data which is read out from the memory, to a host system for processing the original data.
Claims15
A memory control method of controlling an access to a memory for a writing and a readout, the memory control method comprising:
- carrying out a plurality of techniques for code conversion on original data;
- selecting one of the plurality of techniques for said code conversion to produce converted data, based on an amount of 1s in said converted data;
- writing said converted data into said memory;
- and
- outputting reproduced data which is provided by carrying out an inverse transformation of said code conversion on said converted data which is read out from said memory, to a host system for processing said original data.
A memory system, comprising:
- a memory;
- and
- a memory controller for controlling an access to said memory, wherein
- said memory stores converted data which is produced by carrying out a plurality of techniques for code conversion on original data which is processed by a host system and selecting one of the plurality of techniques for said code conversion based on an amount of 1s in the converted data, and
- said memory controller includes a code inverse transformation part that carries out an inverse transformation of said code conversion on said converted data which is read out from said memory, and thereafter outputs reproduced data which is provided as a result of said inverse transformation of said code conversion, to said host system.
A memory control method, comprising:
- carrying out a plurality of techniques for a code conversion on original data;
- and
- selecting one of the plurality of techniques to produce converted data to be written into a memory, based on an amount of 1s in said converted data.
