Title: Dynamic random access memory cell
Inventor: TAMAKOSHI AKIRA
IPC: H01L27/10
Filed: 1990-04-27
Abstract: PURPOSE:To enable a dynamic random access memory cell to dispense with a refreshing operation by a method wherein the memory cell is put in an OFF state when the potential of a data storage node is lower than a potential of high level and in an ON state when the storage node is kept at a potential of high level to keep the storage node high in potential under such a condition that charges are fed from an impurity buried layer. CONSTITUTION:An N-type impurity buried layer 10 provided inside a P-type substrate is formed avoiding a point just under a Tr1 so as to make the bias potential of the transistor Tr1 equal to a substrate potential, a write operation is carried out in such a way that a selected word line WLi is set to a high level to turn the transistor Tr1 ON, and then a potential correspondent to the high or the low level data of a bit line BLj on a drain side is transmitted to a source electrode on a charge storage side. At this point, the gate potential of a Tr2 serving as a storage node is set to a potential correspondent to a high or a low level, and when the gate potential is kept at a high level, the Tr2 is turned ON and a contact point 2' of a charge storage section is kept at the same potential with a buried layer 10, and when the gate potential is kept at a low level, the Tr2 is turned OFF and a contact point 2' of a charge storage section is kept at a low level. In result, a random access memory of this design can dispense with a refreshing operation.

Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent destruction of a gate insulating film due to electric-field concentration on an active layer edge portion in an SOI-MOS. SOLUTION: A field oxide film 20 having a thickness to reach a buried oxide layer 80 is formed in an SOI substrate so as to completely isolate devices and relax electric-field concentration.

When the fuel in the laminated battery 4 is consumed, an electromagnetic opening and closing valve 3 is opened and at the same time the electromagnetic opening and closing valve 3' is opened and then the cracked gas in the fuel supply path is removed. Then, when the electromagnetic opening and closing valve 3' is closed, the liquid fuel is supplied to the fuel chamber of each unit battery that constitutes the laminated battery 4. The voltage of the laminated battery is restored to the normal value, but when the fuel concentration in the fuel chamber is restored up to the preset value, the electromagnetic opening and closing valve 3 is closed and the supply of the liquid fuel is stopped. That is, since the pressurized gas for fuel supply is not required, any high pressure cylinder is not required.
