Abstract
The present disclosure is drawn to, among other things, a method of managing a magnetoresistive memory (MRAM) device. In some aspects, the method includes receiving a configuration bit from a write mode configuration register. In response to determining the configuration bit is a first value, the MRAM device is operated in a NOR emulation mode. In response to determining the configuration bit is a second value, the MRAM device is operated in a persistent memory mode.
Claims20
A method for managing a memory device, comprising:
- receiving a value of a configuration bit;
- in response to receiving the value of the configuration bit, operating the memory device in a NOR emulation mode which includes:
- receiving a write command comprising a starting address and a sequence of data bytes;
- determining that a first set of bytes of the sequence of data bytes written to one or more memory banks in response to the write command has reached a predefined size;
- and
- writing a second set of bytes of the sequence of data bytes over data previously stored from the starting address;
- and
- operating the memory device in a persistent memory mode.

A memory device, comprising:
- a controller configured to:
- receive a value of a configuration bit;
- in response to determining the configuration bit is a first value, operate the memory device in a NOR emulation mode which includes:
- receiving a write command comprising a starting address and a sequence of data bytes;
- determining that a first set of bytes of the sequence of data bytes written to one or more memory banks in response to the write command has reached a predefined size;
- and
- writing a second set of bytes of the sequence of data bytes over data previously stored from the starting address;
- and
- operate the memory device in a persistent memory mode.
