Title: Semiconductor memory and its method of inspection
Inventor: NORUBERUTO UIRUTO
IPC: G11C11/401
Filed: 1994-08-22
Abstract: PURPOSE: To inspect with practically twice as many clock frequencies using a commercially available product tester for a page mode DRAM by providing a mode selection device and a pulse converter device that outputs a clock signal. CONSTITUTION: An address signal and a write signal which are stored in a temporary memory 14 are transmitted by a clock signal CKI to a line address decoder 10, address count device 15 and a data input/output device 13. The clock signal CKI is supplied by a pulse converter device 16 that is driven by an outer clock signal CLK and a signal -TE from a mode selection device 17, to which the signal CLK and a memory control signal are imparted. In a low level state of the signal -TE, each state changeover of the signal CLK is communicated to a pulse at the output end of the device 11; and in a high level state, only the positive state changeover of the signal CLK is communicated to the pulse of the signal CKI. Consequently, at the same data rate, one half is sufficient for the frequency of the signal CLK, which enables the use of a product tester sold on the market.

Inventor: UENO HIDEAKI
IPC: G02F1/1333
Filed: 1990-08-22
Abstract: PURPOSE:To prevent an end part of a substrate from chipping by heating and pressing two glass substrates, which are formed gravitationally to the same curved surfaces with a specific radius of curvature, as to the curved-surface liquid crystal cell, and further performing press working to a smaller radius of curvature. CONSTITUTION:The two glass substrates 1 are dried after ultrasonic-wave cleaning, put one over another across an ITO thin film 2, and mounted on a metallic bottom force installed in a heating furnace equipped with a heater. Then the two glass substrates 1 are heated to the specific temperature and formed to the same curved surfaces having the specific radius of curvature. In a principal forming process, the two glass substrates 1 are heated to the same extent with the gravitational formation and heated and pressed, and the press working is performed to obtain the same curved surfaces which has the smaller radius of curvature are obtained. At this time, compression-directional stress which operates on both the end surfaces of the concave- side substrate and drawing-directional stress which operates on both the end surfaces of the convex-side substrate decrease. Consequently, both the ends of the substrates are prevented from chipping and the gap between the substrates is made uniform.

Abstract: PURPOSE:To prevent an error in recording information from increasing due to a secular change by providing a detecting means for such a sector as to be likely turned into a defective sector in the future at the time of reproducing the information. CONSTITUTION:An error correction circuit 1 is provided with a correction state deciding circuit 3, to which error correction processed information as a result of the error correction processed by a decoding circuit 2 is inputted. The error correction circuit 1 is capable of correcting up to two errors of each C1 parity in the lateral direction, and is also capable of correcting up to two errors of each C2 parity in the longitudinal direction. Now, with regard to a read operation of information from a recording medium without using the max. correction capacity, in the case of at least one infeasible correction processing at the time of decoding the C2, a sector error signal is outputted from the error correction circuit 1 to an external control part, and it is advised that this sector may likely become a defective sector in the future as an error sector. By this method, such a situation that the recording information becomes impossible of read-out is evaded.
