Storage systems with go to sleep adaption

A storage device system, comprising:

• a memory device configured to operate in a standard mode or in a standby mode, wherein the memory device is configured to operate on commands in the standard mode, and the standby mode is lower in power than the standard mode;
• and
• a controller configured to:
• when a first command is completed in the standard mode, switch a mode of the memory device from the standard mode to the standby mode after a delay period subsequent to the completion of the first command unless a second command is received prior to an end of the delay period, wherein a duration of the delay period is adjustable;
• when the second command is received prior to the end of the delay period, decrease the duration of the delay period based on a first value;
• when the second command is received after the end of the delay period, increase the duration of the delay period based on a second value which is different from the first value;
• and
• when a command specifying a new duration is received, reset the duration to the new duration.

A machine-implemented method, comprising:

• operating a memory device in a standard mode or in a standby mode, wherein the standard mode allows the memory device to operate on commands, and the standby mode is lower in power than the standard mode;
• when a first command is completed in the standard mode, switching a mode of the memory device from the standard mode to the standby mode after a delay period subsequent to the completion of the first command unless a second command is received prior to an end of the delay period, wherein a duration of the delay period is adjustable;
• when the second command is received prior to the end of the delay period, decreasing the duration of the delay period based on a first value;
• when the second command is received after the end of the delay period, increasing the duration of the delay period based on a second value which is different from the first value;
• and
• when a command specifying a new duration is received, resetting the duration to the new duration.

An apparatus, comprising:

• means for operating a memory device in a standard mode or in a standby mode, wherein the standard mode allows the memory device to operate on commands, and the standby mode is lower in power than the standard mode;
• when a first command is completed in the standard mode, means for switching a mode of the memory device from the standard mode to the standby mode after a delay period subsequent to the completion of the first command unless a second command is received prior to an end of the delay period, wherein a duration of the delay period is adjustable;
• when the second command is received prior to the end of the delay period, means for decreasing the duration of the delay period based on a first value;
• when the second command is received after the end of the delay period, means for increasing the duration of the delay period based on a second value which is different from the first value;
• and
• when a command specifying a new duration is received, means for resetting the duration to the new duration.
