Abstract
A datum is written to a memory, by splitting a binary word, representative of the datum and an error correcting or detecting code, into a first part and a second part. The first part is written at a logical address in a first memory circuit. The second part is written at the logical address in a second memory circuit. The error correcting or detecting code is dependent on both the datum and the logical address.
Claims15
A method, comprising writing a datum in memory by:
- splitting a binary word, representative of said datum and an error correcting or detecting code, into at least a first part and a second part;
- and
- writing said first part at a logical address in a first memory circuit;
- and
- writing said second part at said logical address in a second memory circuit, wherein said second memory circuit is different from said first memory circuit and is configured to store as many binary words as said first memory circuit;
- wherein said error correcting or detecting code is dependent on both said datum and said logical address.
