Abstract
A configuration of an electronic device is to be simplified. The electronic device includes a magnetoresistive effect memory, a memory control unit, and a processing unit. The magnetoresistive effect memory holds first data to be written with verification and second data to be written without verification. The memory control unit writes the first data and the second data into the magnetoresistive effect memory and verifies the first data. The processing unit performs processing based on the first data and the second data.
Claims13
An electronic device, comprising:
- a magnetoresistive effect memory configured to hold first data and second data, wherein the magnetoresistive effect memory includes a common region to hold one of the first data or the second data;
- and
- circuitry configured to:
- write the first data and the second data into the magnetoresistive effect memory, wherein
- the first data is written for a first time period and the second data is written for a second time period, and
- the first time period is longer than the second time period;
- verify the written first data;
- read switching information from the magnetoresistive effect memory;
- control a switching operation between the first data and the second data for the common region based on the switching information;
- write the one of the first data or the second data in the common region based on the switching operation;
- select the one of the first data or the second data from the common region;
- and
- execute a processing operation based on the selected one of the first data or the second data.
