Abstract

The embodiment of the present application relates to the field of data storage technology, and provides an access control method, device, and electronic device for a storage device. The method includes: receiving an access request for the address space of the storage device, the access request carrying target address information ; Determine the target address space corresponding to the target address information according to the mapping relationship between the address information and the address space type, the address space type includes a storage address space, a test address space, and a repair address space; access timing control information of the access request; and access the target address space according to the control information. The embodiment of the present application can effectively reduce access time and improve access efficiency.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data storage, and in particular, to an access control method, device, and electronic device for a storage device. Background technique [0002] Electrically programmable fuse (efuse) is a memory device that can only be written once. Usually, the non-programming state is 0, and the state after programming is 1. It is often used in system-on-chip (soc) to store Some identity documents (identity document, id) or secret keys and other information. The read and write sequence of efuse is quite special, and it needs a specially designed circuit to realize it. In addition to read and write operations, it is also necessary to design a test circuit to test efuse after generation and processing. Some efuses also support the function of repairing the damaged efuse bit (binary digit, bit), which also requires external control circuit support. [0003] The current solution is to control ...
