Abstract
A measuring unit measures a time (T) of a command interval by setting the end of a command generated from an upper apparatus to a start timing or by setting the start of the reception of the next command to a stop timing. A timing deciding unit varies a plurality of timings to perform a power saving on the basis of the measurement time of the command interval which was measured by the measuring unit. A power save control unit controls the apparatus to a power saving mode for a time interval from the timing decided by the timing deciding after the end of the execution of the command received from said upper apparatus until a timing when a next command is obtained.
Claims18
A memory apparatus comprising:
- measuring means for measuring a time of a command interval from a timing when an execution of a command generated from an upper apparatus is finished to a timing when a next command is received;
- timing deciding means for varying a timing to perform a power saving on the basis of the measurement time of the command interval measured by said measuring means;
- and
- power save control means for controlling the apparatus to a power saving mode for a time interval from the timing decided by said timing deciding means after the end of the execution of the command received from said upper apparatus until a timing when a next command is obtained.
A memory apparatus comprising:
- measuring means for measuring a time of a command interval from a timing when an execution of a command generated from an upper apparatus is finished to a timing when a next command is received;
- deciding means for deciding one or a plurality of circuit units to be subjected to a power saving in accordance with the measurement time of the command interval by said measuring means;
- and
- power save control means for controlling the apparatus to a power saving mode for a time interval from the timing decided by said timing deciding means after the end of the execution of the command received from said upper apparatus until a timing when a next command is obtained.
