Patent JP-H1040700-A (JP)
Title: Semiconductor chip with built-in self-test function
Inventor: ROBERT D ADAMS
IPC: G11C29/12
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To reduce the development period by combining predesigned logic blocks and structuring a chip with a built-in self-test function. SOLUTION: A built-in self-test function is structured with plural logic blocks. Each logic block is arranged in proximity to a corresponding memory block, with the peculiar test signal generated locally. The logic blocks are prepared as a predesigned library and selectively combined as necessary. For instance, a clock generator 303 forms a clock 361 to transmit to all other logic blocks. An address counter 301, through a signal bus 351, transmits an address to a memory to be tested. A data generator 306 tests the least significant bit of a word address to form a word line stripe pattern consisting of '1' or '0'.

IPC: H01J31/12
Filed: 1989-03-13
Abstract: PURPOSE:To increase the pressure withstand and enhance the sealing performance by separating a metal vessel to be coupled with a flat glass into two, performing coupling with glass by frit glass and metal vessel with small wall thickness on the outside, and allowing the atmosphere pressure applied to a vacuum vessel to be borne by a pressure withstand vessel located inside which is not frit jointed. CONSTITUTION:By frit glass 16, an exterior vessel 15 shaped from a thin metal sheet is sealed fast to a face glass 10 at a flange part on the periphery. A pressure withstand vessel 17 shaped from a thick metal plate bears the atmospheric pressure applied to vessel when inside the device is evacuated. When the inside is evacuated, this exterior vessel 15 receives the action of atmospheric pressure, which is however borne by the pressure withstand vessel 17 situated inside, so that there is no fear of breakage of the exterior vessel 15. Because it is made of thin metal sheet, there is no risk either of crack initiation at the joint part when to be jointed with glass.
