Device and method for scheduling commands in a solid state drive to reduce peak power consumption levels

A solid-state storage device comprising:

• a processor;
• an I/O interface configured to allow communication between the processor and a host computer system, wherein the processor is configured to receive an instruction from the host computer system via the I/O interface;
• a controller unit connected to the processor, the controller unit further connected to one or more memory bus channels, wherein each memory bus channel is connected to one or more flash memory devices, the controller unit configured to initiate a processing of a command issued by the processor to a flash memory device in response to the processor receiving the instruction from the host device, the controller unit further configured to assign a timestamp to the command;
• and
• a non-transitory storage memory connected to the controller unit, the storage memory storing a look-up table having one or more rows containing time regions when the command can be processed, each time region have a type identifier and a start time and an end time,
• wherein the controller unit is further configured to evaluate a time difference between a timestamp of a command to be initiated and processed and a timestamp of a command previously initiated and being processed, and to retrieve the row of the look-up table indexed by the time difference, and if the time difference is found within any time region of a row of the look-up table having a type identifier of a first type, immediately initiating the processing of the command, and if the time difference is found within any time region of a row of the look-up table having a type identifier of a second type, initiating processing of the command at the end time of the time region with the second type identifier.
