Title: Volatile semiconductor memory device
Inventor: NISHI TOSHIYA
IPC: H01L21/8242
Filed: 1989-03-10
Abstract: PURPOSE:To maintain a large degree of freedom in order to optimize various transistors and to enhance a performance furthermore by a method wherein a gate insulating film of a transfer transistor is formed to be thicker than a gate insulating film of a transistor other than the transfer transistor. CONSTITUTION:Gate insulating films IG1, IG2 of a transistor in a memory cell part MC are formed to be thick as compared with the gate insulating film IG2 of a transistor in a part PC other than the memory cell. Accordingly, film thicknesses of the gate insulating film in the transfer transistor and the gate insulating film in the transistor in the part other than the memory cell can be decided independently of each other. Thereby, this device can be optimized so as to deal with various problems caused when a switching speed is enhanced, a short channel is eliminated or a life of a memory cell is shortened by a situation that the gate insulating film captures carriers; when these problems are solved, performance can be enhanced furthermore.

Abstract: PURPOSE:To prevent each grid electrode from being warped by providing a pair of implantation blocks which are deeply implanted into an insulating support body at the central part on both sides of the first or second grid electrode and a low step blocks which are shallowly retained in the insulating support body on both sides of the implantation blocks. CONSTITUTION:A pair of implantation blocks 44a and 44b implanted into an insulating support body are provided at the central part on both sides of the support body 43a of the first or second grid electrode 43 and low step blocks 45a, 45b, 45c, and 45d are provided on both sides of these implantation blocks 44a and 44b. When the implantation blocks 44a and 44b are implanted into the insulating support body, these low step blocks are retained more shollowly than these implantation blocks and the width of the insulating support body is made narrower than the outer width 46 of the low step blocks. For the expansion of the grid electrode dimensions by thermal expansion, this permits the low step blocks to slide along with the insulating support body centering around the implantation blocks and to escape in the width direction on the sides. As the result, the implantation blocks can hold only one fixed point and the grid electrode can be prevented from being warped.

IPC: G11C11/406
Filed: 1986-03-14
Abstract: PURPOSE:To hold the data without refresh from a CPU by applying normal access to a dynamic RAM block selected at access and applying refresh to other block. CONSTITUTION:A forced select signal 15 is made active by a DMA signal 13 at the access from a direct memory access controller DMAC and all dynamic RAMs 6-1-6-4 are made active. Address information is outputted to an address line 8 at the same time at access from a CPU and select inhibition signals 16-1-16-4 are made active (one is inactive) other than the signal corresponding to decode signals 3-1-3-4 because the signal 13 is active. Thus, only to the selected RAMs 6-1-6-4, a strobe signal (any one of signals 18-1-18-4) is outputted, normal access is applied and refresh is applied to other dynamic RAM.

Abstract: PURPOSE:To ensure signal decoding at a base station by using a satellite channel and stopping the increase in a signal transmission time due to increase in the number of burst signals when a mobile station sends signals divided into plural burst signals to the base station. CONSTITUTION:When a transmission request takes place in a mobile station 70, a control section 28 generates a transmission signal and informs a control section 50 of a base station of it and when the signal cannot be sent by one burst signal, the control section 28 of the mobile station 70 divides the signal into plural blocks. Then a head block among them is inputted to an error check multiplexer 30, a synchronization word is multiplexed onto the multiplexed signal by using a transmitter 31 and the base station 60 sends the burst signals by random access. When a receiver 39 receives the signals, a demultiplexer 40 demultiplexes the error multiplexed on the received burst signal and a block detector 41 detects whether or not the signal is the burst signal and when the signal is the burst signal, it is given to a collision control bit generator 40, in which a multiplexed reply signal is generated.

Filed: 1987-03-12
Abstract: PURPOSE:To ensure smooth rise processing for each system that uses system control data to be exclusively used by securing the coincidence between the starting order of a rise program and the lock acquiring order. CONSTITUTION:Respective rise processors 3 and 8 receive a system rise requests and load the rise programs stored in a secondary memory 4 into primary memories 2 and 7 of their own systems respectively. Then the processors 3 and 8 perform lock acquiring processing for a lock mechanism 5. In case the locks are acquired in its own system since the locks are not acquired by processors 3 and 8 of another system, the execution of the rise program is started by processors 1 and 6 of its own system. When the execution of the rise program is ended, lock release processing is carried out to allow the start of the program of another system. If the lock acquisition processing fails, this processing is repeated and the execution of the rise program of its own system is started when a lock state is released after the end of the rise processing of another system.
