Abstract
A magnetoresistive solid-state storage device (MRAM device) uses storage cellsarranged in many arraysto form a macro-arrayFor fast access times and to reduce exposure to physical failures, each unit of data (e.g. a sector) is stored with a few sub-units (e.g. bytes) in each of a large plurality of the arraysAdvantageously, the plurality of arraysare accessible in parallel substantially simultaneously, and a failure in any one array affects only a small portion of the data unit. Optionally, error correction coding (ECC) is employed to form encoded data with symbols which are stored according to preferred embodiments which further minimise exposure to physical failures.
