Abstract:
A magnetic detection circuit for a magnetic random access memory (MRAM) is provided. The magnetic detection circuit includes a sensing array including a plurality of sensing cells and a controller. Each of the sensing cells includes a first magnetic tunnel junction (MTJ) device. The controller is configured to access the first MRAM cells to detect the external magnetic field strength of the MRAM. The controller determines whether to stop the write operation of a plurality of memory cells of the MRAM according to the external magnetic field strength of the MRAM, and each of the memory cells includes a second MTJ device. The first MTJ device is smaller than the second MTJ device.

Claim (Index 8):
A magnetic random access memory (MRAM), comprising:\n a plurality of sensing cells, wherein each of the plurality of sensing cells comprises a first magnetic tunnel junction (MTJ) device; a plurality of memory cells arranged in at least one memory array, wherein each of the plurality of memory cells comprises a second MTJ device; a controller coupled to the plurality of sensing cells, and configured to write first data into the plurality of sensing cells and read second data from the plurality of sensing cells after the first data is written; and an access circuit coupled to the plurality of memory cells, and configured to access the plurality of memory cells, wherein the controller is configured to obtain difference between the first data and the second data and to control the access circuit to stop writing the memory array when the difference between the first data and the second data indicates that external magnetic field strength of the MRAM is greater than a threshold strength.
