Abstract

The invention discloses a magnetic random access memory. The magnetic random access memory comprises storage bits with at least two working frequencies; each storage bit comprises a magnetic tunnel junction, a metal wire and a field effect transistor; and the storage bits with the different working frequencies are same in magnetic tunnel junction diameter but different in field effect transistor width, or the storage bits with the different working frequencies are different in magnetic tunnel junction diameter but same in field effect transistor width. According to the magnetic random access memory, the storage bits with the different frequencies are located on a same chip, and the working frequency of the memory can be increased along with the increment of the calculation speed of a processor and the data throughput, so that the overall working performance of a system is improved; and the working frequency of the memory can be reduced according to an actual demand when the processor is relatively idle, so that the overall voltage, heating and working energy consumption of the system can be reduced and the service life and reliability of the memory are improved.

Description

technical field

[0001] The invention relates to the technical field of memory design, in particular to a magnetic random access memory. Background technique

[0002] In recent years, the gap between the operating frequency of the processor and the memory has widened year by year, and the operating frequency of the memory has become a bottleneck that limits the improvement of the data processing performance of the computer system. For example, the central processing unit of a computer generally has a certain overclocking capability, but the operating frequency range of memories such as memory is limited, which hinders the increase of the operating frequency of the central processing unit. The operating frequency of the memory depends on the physical properties of the storage bits themselves. Therefore, choosing a memory with high-frequency operation capability and a wide operating frequency range to store bits can effectively help the system improve computing performance. ...
