Completion entry throttling using data storage controller

A data storage controller for use with a non-volatile memory (NVM) having a set of memory arrays configured to store data in pages with individual page sizes, comprising:

• a processing system configured to
• obtain completion entries indicative of completion of commands by the arrays of the NVM for reporting to a host device, the completion entries obtained at non-uniform time intervals;
• store the completion entries in an internal queue within the data storage controller;
• and
• send at least some of the completion entries from the internal queue to the host device using output time intervals that are more uniform than the non-uniform time intervals while controlling a duration of the output time intervals based on sizes of individual pages in the arrays of the NVM, including using a first output interval duration with an array having a first individual page size and using a second output interval duration with an array having a second individual page size, wherein the first output interval duration differs from the second output interval duration and the first individual page size differs from the second individual page size.

An apparatus coupled to a non-volatile memory (NVM) having a set of memory arrays that store data in pages with individual page sizes, comprising:

• means for obtaining values at non-uniform time intervals indicative of completion of commands by the NVM for reporting to a host device;
• means for temporarily storing the values;
• means for sending at least some of the values to the host device at time intervals that are more uniform than the non-uniform time intervals;
• and
• means for controlling a duration of the time intervals that are more uniform than the non-uniform time intervals based on sizes of individual pages in the arrays of the NVM, including using a first output interval duration with an array having a first individual page size and using a second output interval duration with an array having a second individual page size, wherein the first output interval duration differs from the second output interval duration and the first individual page size differs from the second individual page size.
