Techniques for efficient error correction code implementation in a system

A memory system with folding error correction, the memory comprising:

• at least a memory bank;
• means for generating error correction code for data to be written to said memory system;
• means for writing said received data to a location in said memory bank corresponding to a received address of said received data;
• means for generating an error correction code write address in said memory bank based on said received address;
• and,
• means for writing said error correction code to said error correction code write address.

A memory controller with folding error correction, the controller comprising:

• means for accessing a first memory bank;
• means for accessing a second memory bank;
• means for generating error correction code for received data to be written to said first memory bank;
• means for writing said received data to a location in said first memory bank corresponding to a received address of said received data;
• means for generating an error correction code write address in said second memory bank based on said received address;
• and,
• means for writing said error correction code to said error correction code write address.

A memory controller with folding error correction, the memory controller comprising:

• means for generating error correction code for data to be written to a memory bank;
• means for writing said received data to a location in said memory bank corresponding to a received address of said received data;
• means for generating an error correction code write address in said memory bank based on said received address;
• and,
• means for writing said error correction code to said error correction code write address.

A method for placing an error correction code respective of a data received by a memory controller with folding error correction, the method comprising the steps of:

• writing said data into a first memory bank of the memory;
• generating the error correction code respective of said data;
• generating an address in a second memory bank of the memory;
• and,
• writing said error correction code to said address in a second memory bank.

A method for retrieving data and its respective error correction code of a read address received by a memory controller with folding error correction, the method comprising the steps of:

• reading the data from a first memory bank of the memory;
• generating an address of a second memory bank of the memory for retrieval of said respective error correction code;
• retrieving said error correction code respective of said data;
• and
• returning the data read after error correction.

A method for placing an error correction code respective of a data received by a memory controller with folding error correction, the method comprising the steps of:

• writing said data into a memory bank of the memory;
• generating the error correction code respective of said data;
• generating an address in said memory bank of the memory;
• and,
• writing said error correction code to said address in said memory bank.

A method for retrieving data and its respective error correction code of a read address received by a memory controller with folding error correction, the method comprising the steps of:

• reading the data from a memory bank of the memory;
• generating an address in said memory bank for retrieval of said respective error correction code;
• retrieving said error correction code respective of said data;
• and,
• returning the data read after error correction.
