Physical quantity distribution sensor, method of driving said sensor and method of producing said sensor

摘要

A physical quantity distribution sensor is disclosed. The sensor comprises: a plurality of sensor/storage sections each having a sensor element for sensing a received physical quantity and a storage element for storing the information of physical quantity sensed by the sensor element; a selector for selecting at least one of the sensor/storage sections; and a plurality of buffers each capable of detecting and supplying the information stored in at least one selected sensor/storage section. This sensor further comprises at least one selection signal transfer line for transferring an output of the selector. Power supply input portions of the buffers are connected to the selection signal transfer line, and the buffers are operated using, as a power voltage, an output of the selector entered into the buffers through the selection signal transfer line.
