AI Technical Summary
Technical Problem
In existing technologies, QLC solid-state storage does not consider the error characteristics of each page when allocating addresses, resulting in some data being concentrated in high pages (such as MSB and TSB), which affects read performance and user experience.
Method used
By acquiring snapshot information and using mapping rules, adjacent logical block addresses are allocated to different physical regions, generating offset snapshots and index sets. This avoids data concentration in high pages and optimizes the address allocation order using multi-matrix calculations.
Benefits of technology
It improves read performance and user experience, reduces read latency, extends device lifespan, and optimizes storage space utilization.

Abstract
Embodiments of the present disclosure provide an address allocation method and device, a storage medium and an electronic device, and relate to the technical field of computers. The method comprises: in response to a write request, obtaining snapshot information; and according to a mapping rule, allocating a physical block address corresponding to a logical block address of at least one data by using the snapshot information; wherein the snapshot information is used to allocate adjacent logical block addresses to physical block addresses in different areas. In this way, by allocating adjacent logical block addresses to different physical areas, the situation of some data being concentrated in high pages is avoided, thereby improving reading performance and user experience.
