Abstract

Disclosed are a chip, a chip-based data access method, a storage medium, and an electronic device. The chip includes: a first chip domain and a second chip domain, where a functional safety level of the first chip domain is higher than that of the second chip domain, and the first chip domain is configured to generate a data access request for the second chip domain; and an isolation circuit, configured to perform a memory access operation on a storage space of the second chip domain based on the data access request, and return a request execution result of the data access request to the first chip domain based on an actual feedback status of the second chip domain for the memory access operation, so that the storage space of the second chip domain is used as an extended storage space of the first chip domain.
