Samsung patents memory system that adjusts address sizes for faster data access
This patent describes a memory system where the main processor sends data requests using large address blocks, but the memory device converts them into smaller, more precise blocks before accessing the actual storage cells. This two-step translation process allows the system to manage memory space more efficiently by using different page sizes at different stages.
In the filing’s own words
A memory system includes a host and a memory device. The host is configured to translate a virtual address into first physical address based on a first page size and issue a memory access request including the first physical address. The memory device is configured to receive the memory access request from the host, translate the first physical address into a second physical address based on a second page size that is smaller than the first page size in response to the memory request, and access memory cells using the second physical address.
What exactly they claim (claim 1)
1. A memory device comprising: a memory processing unit configured to receive a memory access request including a first physical memory address based on a first page size from a host, translate the first physical address based on the first page size into a second physical address based on a second page size that is smaller than the first page size, and access memory cells of the memory device using the second physical address.
