摘要:
A semiconductor memory device has a plurality of memory cells in an array, into which the memory cells data is writable, and which can subsequently be read. Each memory cell has a switching element with one terminal connected to a bit line of the array another terminal connected to at least one ferroelectric capacitor, and a control terminal connected to a word line. The cell may then be operated to detect the change in polarization of the ferroelectric capacitor when a voltage is applied which is not sufficient to cause a change of state of the ferroelectric capacitor. Alternatively, a ferroelectric capacitor and a capacitor other than a ferroelectric capacitor is connected to the switching element. In a further alternative, a plurality of ferroelectric capacitors are connected to the switching element, so that different data are writable into each.

摘要:
A monolithic complementary semiconductor device comprising n-type and p-type well regions separated by a dielectric isolation region extending from the surface into the substrate region. The well region includes a highly doped buried region which is located at the bottom of the well region and separates an active region in the wall from the substrate region. The isolation region is deeper than the buried region. The well-to-well isolation is enhanced by the combination of the buried region and the deep dielectric isolation region. Packing density and the high speed operation can also be improved.

A resource management system includes a resource management device that manages a usage of a resource, a reservation management device that manages a reservation for the resource, and a communication relay device that communicates with the resource management device. The resource management device receives reservation information transmitted from the reservation management device. The reservation information is information on the reservation for the resource. The resource management device transmits, to the communication relay device, a request for identification information identifying the communication relay device. The resource management device receives the identification information, which is transmitted from the communication relay device in response to the request. The identification information is used to execute an event associated with the reservation information. The resource management device transmits, to an operation display terminal that displays a usage status of the resource, the identification information and a password that is associated with the identification information.
