Condensing Logical to Physical Table Pointers in SSDs Utilizing Zoned Namespaces

A storage device, comprising:

• a non-volatile storage unit, wherein a capacity of the non-volatile storage unit is divided into a plurality of zones, and wherein the non-volatile storage unit comprises a plurality of dies, each of the plurality of dies comprising a plurality of erase blocks, and each of the erase blocks comprising a plurality of wordlines and pages;
• a volatile memory unit, wherein the volatile memory unit stores a first logical to physical address table, the first logical to physical address table associating logical block addresses of data to a physical address of where the data is stored in the non-volatile storage unit;
• and
• a controller coupled to the non-volatile storage unit and the volatile memory unit, wherein the controller is configured to:
• write first data associated with one or more first commands to a first erase block in a first zone of the plurality of zones;
• update the first logical to physical address table stored in the volatile memory unit, wherein updating the first logical to physical table comprises associating a pointer to the first zone and the first data;
• receive a read command to read the first data;
• identify a first logical block address of the first data;
• read the pointer associated with the first zone to determine the first data is stored within the first zone;
• calculate an offset of erase blocks to determine the first data is stored in the first erase block;
• and
• calculate an offset of pages and wordlines within the first erase block to find the first data.
