METHOD OF READING AND WRITING TO A SPIN TORQUE
MAGNETIC RANDOM ACCESS MEMORY WITH ERROR CORRECTING CODE |
摘要 |
A method includes destructively reading bits of a spin torque magnetic random access memory, using error correcting code (ECC) for error correction, and storing inverted or non-inverted data in data-store latches. When a subsequent write operation changes the state of data-store latches, parity calculation and majority detection of the bits are initiated. A majority bit detection and potential inversion of write data minimizes the number of write current pulses. A subsequent write operation received within a specified time or before an original write operation is commenced will cause the majority detection operation to abort. |
