Direct logical-to-physical address mapping for sequential physical addresses

A memory system, comprising:

• one or more memory devices;
• and
• processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
• receive a plurality of write commands for writing a plurality of data sets;
• write, in accordance with receiving the plurality of write commands, first data sets of the plurality of data sets to first sequential physical addresses that are associated with sequential logical addresses of the memory system and a first sequence number group;
• write, in accordance with writing the first data sets to the first sequential physical addresses, second data sets of the plurality of data sets to second sequential physical addresses that are associated with an overlapping portion of the sequential logical addresses of the memory system and a second sequence number group, wherein the first sequential physical addresses precede the second sequential physical addresses and the first sequence number group precedes the second sequence number group;
• determine a sequence number group of a last data set written at the memory system in accordance with writing the second data sets to the second sequential physical addresses;
• and
• read, in accordance with determining the sequence number group, a data set from a physical address of the memory system.

A memory system, comprising:

• one or more memory devices;
• and
• processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
• receive a plurality of write commands for writing a plurality of data sets;
• determine a sequence number group of a last data set written at the memory system, wherein determining the sequence number group is in accordance with a result of dividing a sequence number associated with the last data set written at the memory system by a quantity of blocks of the memory system for storing data for sequential logical addresses;
• determine a physical address of a data set in accordance with a logical address of the data set, a logical address of the last data set written at the memory system, and the sequence number group of the last data set written at the memory system;
• and
• read, in accordance with determining the physical address, the data set from the physical address of the memory system.

• receive a plurality of write commands for writing a plurality of data sets;
• write, in accordance with receiving the plurality of write commands, first data sets of the plurality of data sets to first sequential physical addresses that are associated with sequential logical addresses of the memory system and a first sequence number group;
• write, in accordance with writing the first data sets to the first sequential physical addresses, second data sets of the plurality of data sets to second sequential physical addresses that are associated with an overlapping portion of the sequential logical addresses of the memory system and a second sequence number group, wherein the first sequential physical addresses precede the second sequential physical addresses and the first sequence number group precedes the second sequence number group;
• determine a sequence number group of a last data set written at the memory system in accordance with writing the second data sets to the second sequential physical addresses;
• and
• read, in accordance with determining the sequence number group, a data set from a physical address of the memory system.
