A body weight threshold determination unit determines that the body weight of a user on a bed is at a body weight threshold or higher, and a center-of-gravity position area determination unit determines that the center-of-gravity position thereof has moved to an abnormal position (monitored area). In such a case, the bed user is detected to be in an abnormal position when a body weight center-of-gravity position monitoring unit detects that such a state has continued for a prescribed length of time or longer. When a back-raising operation has been carried out, a movable bedboard determination unit inputs the movable bedboard information, and a monitored area adjustment unit adjusts the monitored area. The monitored area is thereby constantly set to a suitable area in accordance with the state of the movable bedboard. In this manner, the combined information of the body weight information and center-of-gravity position information of the user is determined, whereby the movement of the user can be more accurately monitored with fewer misdetections, high detection accuracy, and high reliability in an electric bed having a movable bedboard.

A cache record error storage having at least one error record, and a hard error storage having at least one hard error record, are provided for keeping track of errors detected when accessing cache records of the cache storage. In particular, when an error is first detected for a particular cache record, one of the error records in the cache record error storage is allocated to store a cache record identifier for that cache record, and an associated count value is set to a first value. Further, if an error is detected when accessing a cache record, a correction operation is performed in respect of that currently accessed cache record, and access to that currently accessed cache record is then re-performed. Each time an error is detected for subsequent accesses to that cache record, the count value is incremented, and each time an error is not detected when that cache record is accessed, the count value is decremented. If the count value reaches a predetermined threshold value, then the cache record identifier is moved from the cache record error storage to an error record of the hard error storage. Any cache record whose cache record identifier is stored in the hard error storage is logically excluded from the plurality of cache records of the cache storage for the purposes of subsequent operation of the cache storage. Such an approach provides a hardware mechanism that automatically identifies and corrects hard and soft errors, but only masks from further use those cache records affected by hard errors.
