摘要： A method and memory device is provided for reading data from an ECC word of a plurality of reference bits associated with a plurality of memory device bits and determining if a double bit error in the ECC word exists. The ECC word may be first toggled twice and the reference bits reset upon detecting the double bit error.

摘要： In some examples, a memory device is configured to load multiple pages of an internal page size into a cache in response to receiving an activate command and to write multiple pages of the internal page size into a memory array in response to receiving a precharge command. In some implementations, the memory array is arranged to store multiple pages of the internal page size in a single physical row.

摘要： A method includes destructively reading bits of a spin torque magnetic random access memory and immediately writing back the original or inverted values. A detection of the majority state of the write back bits and a conditional inversion of write back bits are employed to reduce the number of write back pulses. A subsequent write command received within a specified time or before an original write operation is commenced will cause a portion of the write back pulses or the original write operation pulses to abort. Write pulses during subsequent write operations will follow the conditional inversion determined for the write back bits during destructive read.
摘要翻译： 一种方法包括破坏性地读取自旋扭矩磁随机存取存储器的位并立即写回原始值或反相值。 采用回写位的多数状态的检测和回写位的条件反转来减少回写脉冲的数量。 在指定时间内或在原始写入操作开始之前接收到的后续写入命令将导致回写脉冲的一部分或原始写入操作脉冲中止。 在后续写入操作期间的写入脉冲将遵循在破坏性读取期间为回写位确定的条件反演。

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.
