Abstract

The invention discloses a data reading method. The method comprises the following steps of: receiving a reading operation request which carries a first address by a controller of a memory, wherein thereading operation request is used for indicating the controller to carry out reading operations on the first address; carrying out N reading operations on the first address by the controller of the memory, and obtaining N pieces of data read by the N reading operations; judging whether the N pieces of data are consistent or not by the controller of the memory; and if the controller judges that the N pieces of data are consistent, sending response information for responding the reading operation request by the controller, wherein the response information comprises any one of the N pieces of data. The invention furthermore provides a memory. By adoption of the data reading method and the memory, benefit is brought to solve the problem that data of memories is tampered and leaked in the datareading process.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data reading method and a memory. Background technique [0002] Data reading operations are the most common operations in the field of data processing. Usually, the process of data reading operation is that the data reading device sends a read operation command to the data storage unit, and after receiving the read operation command, the data storage unit obtains the data corresponding to the address according to the address carried in the read operation command, and sends The data corresponding to the address is returned to the data reading device. According to the above process, the data reading device obtains the data corresponding to the address. However, in the process of the data reading device performing the above-mentioned reading operation, the attacker obtains the address carried in the reading operation command and the data corresponding to the changed address by mon...
