Methods and apparatus for read disturb detection based on logical domain

A solid state drive (SSD) comprising:

• a non-volatile memory (NVM);
• and
• a controller communicatively coupled to a host device, a local memory device, and the NVM,
• wherein the controller is configured to:
• store read access counts in the local memory device, wherein the read access counts correspond to a number of times logical block addresses are read accessed by the host device, wherein the logical block addresses respectively correspond to physical memory address locations of the NVM, and wherein adjacent logical block addresses correspond to at least some non-adjacent physical memory address locations in the NVM;
• determine when one or more of the stored read access counts of the logical block addresses exceed a predefined threshold number of access counts;
• and
• trigger a Read Disturb prevention process for physical memory address locations in the NVM corresponding to a logical block address having corresponding read access counts determined to exceed the predefined threshold number of access counts.
