Title: Semiconductor storage device
Inventor: KATO YOSHIYUKI
IPC: G11C11/407
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To relax design conditions and achieve a storage device capable of high frequency operation by providing decoder members, register circuits, and a word driver circuit to select a decoder output state and a word line according to an internal pulse state. SOLUTION: When a decoder D1 is selected by levels of external address inputs A0 and A1, the decoder D1 of a decoder member 1 outputs selection H to its output (a node N1). When an internal pulse is nonselection L, H is transferred to a node N2 to turn on a transmission transistor TR1, and a node N3 is turned to L by an invertor I1. At the same time, a P channel MOSTRP1 is turned on to turn a node 4 to VCC (=H), and an output of a register circuit 2 (a node X0), that is an input of a word driver WD1 is nonselected. Then, when an inner pulse is selection H, an input of the word driver WD1 is selected.

Title: Allocation management system for dynamic memory
Inventor: KOBAYASHI AKIRA
IPC: G06F12/16
Filed: 1991-03-07
Abstract: PURPOSE:To easily invalidate the memory allocation processing if desired after a memory is dynamically acquired in a module. CONSTITUTION:A memory acquisition management part 11 acquires a memory and registers the position of the memory into a memory acquisition table. Thus the memory acquired through the module having a memory request. A memory release management part 12 retrieves a fact whether the position of the acquired memory is registered in the memory acquisition table or not. If so, the memory position is deleted out of the table and the memory is released. If not, the memory position is registered into a memory release table.

A stop diameter and an F value, which makes the cross-section area by the final surface out of the final movable lens groups of the zoom lens for the luminous flux whose image is formed on the optical axis of the image pickup surface the fixed value, are calculated and stored by an arithmetic processing part 8. Besides, a shutter speed and the F value for obtaining proper exposure obtained from a photometry device are calculated and compared with the threshold F value. When the F value is smaller than the threshold F value, an exposure action is started. However, when it is larger than the threshold F value, it is limited to the threshold F value and calculated again. Then, the exposure is executed. Thus, the adverse effect on an image caused by foreign matters such as the dust in the photographing luminous flux is reduced.
