Supporting multiple active regions in memory devices

A method comprising:

• maintaining a plurality of context data structures, each context data structure corresponding to an active region of a plurality of active regions of a memory device, wherein each context data structure comprises an indicator characterizing the corresponding active region as one of:
• open or closed, and wherein each context data structure comprises a number of padding operations performed with respect to the corresponding active region;
• receiving a write request directed to a first active region of the plurality of active regions, wherein the first active region is associated with a first context data structure of the plurality of context data structures;
• responsive to determining that a first indicator of the first context data structure characterizes the first active region as closed, identifying a second active region of the plurality of active regions;
• identifying a buffer associated with the second active region of the plurality of active region, wherein the buffer stores host data;
• padding the host data in the buffer to a predetermined size;
• flushing the buffer to the second active region of the memory device;
• incrementing the number of padding operations performed with respect to the second active region;
• updating a second context data structure of the second active region of the memory device, wherein the second context data structure comprises the number of padding operations performed with respect to the second active region;
• and
• updating the first indicator of the first context data structure to characterize the first active region of the memory device as open.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• maintaining a plurality of context data structures, each context data structure corresponding to an active region of a plurality of active regions of a memory device, wherein each context data structure comprises an indicator characterizing the corresponding active region as one of:
• open or closed, and wherein each context data structure comprises a number of padding operations performed with respect to the corresponding active region;
• receiving an append request directed to a first active region of the plurality of active regions, wherein the first active region is associated with a first context data structure of the plurality of context data structures;
• responsive to determining that a first indicator of the first context data structure characterizes the first active region as closed, identifying a second active region of the plurality of active regions;
• identifying a buffer associated with the second active region of the plurality of active region, wherein the buffer stores host data;
• padding the host data in the buffer to a predetermined size;
• flushing the buffer to the second active region of the memory device;
• incrementing the number of padding operations performed with respect to the second active region;
• updating a second context data structure of the second active region of the memory device, wherein the second context data structure comprises the number of padding operations performed with respect to the second active region;
• and
• updating the first indicator of the first context data structure to characterize the first active region of the memory device as open.
