An integrated circuit includes multiple memory circuits including memory cell arrays different in size, a BIST circuit which has a cell sequential transition test processor and which outputs a test cell address, a transition direction specification signal and an active signal. The integrated circuit has adjustment circuits which are provided respectively for the memory circuits and which replace the test cell address with the test cell address in a memory cell array area, or which convert the active signal into a signal indicating non-execution when the test cell address outputted from the BIST circuit corresponds to a cell in a virtual cell array being in an area outside the memory cell array.

Provided is a method of producing a heat-resistant inorganic textile formed of a heat-resistant inorganic fiber that includes an inorganic base fiber and a heat-resistant inorganic ceramic layer that coats the inorganic base fiber, the method including the steps of: (1) subjecting an inorganic base textile formed of the inorganic base fiber to a coating treatment with a meltable silicone resin or a curable silicone composition, thereby forming a meltable silicone resin layer or curable silicone composition layer that coats the inorganic base fiber, (2) subjecting the meltable silicone resin layer to a non-melting treatment, thereby forming a non-melting silicone resin layer, or subjecting the curable silicone composition layer to curing, thereby forming a silicone cured product layer, and (3) heating the non-melting silicone resin layer or silicone cured product layer under a non-oxidizing atmosphere, at a temperature within a range from 400 to 1,500° C., thereby generating a heat-resistant inorganic ceramic layer. The method enables favorable conservation of resources and is economically beneficial. The heat-resistant inorganic textile produced by the method exhibits excellent heat resistance and strength, and is ideal as a material for an exhaust gas filter.

A memory card includes: a package in the form of a thin plate made of an insulating material and configured to be inserted into and removed from a slot of an external apparatus; a plurality of contacts provided on the package and configured to transmit a signal to and from the external apparatus; the contacts being juxtaposed in a direction perpendicular to a loading/unloading direction, in which the memory card is loaded into or unloaded from the external apparatus, in a region of a flat face, which is one of faces of the package in a thicknesswise direction, except locations on the opposite sides in the direction perpendicular to the loading/unloading direction; and a pair of side labels adhered to the locations on the opposite sides of the upper face of the package and extending along the loading/unloading direction.

A card tray to be mounted to a memory card can make the memory card mountable in a card slot for memory cards conforming to standards different from those to which the memory card conforms. The card tray has a main body and a recessed mount section. The recessed mount section is formed such that the holder of a second memory card can be mounted to one of the major surfaces of the main body. A memory-card-mounted body is produced when the second memory card is mounted to the recessed mount section. The card tray is configured such that, when the first memory card is placed on the memory-card-mounted body with the left and right edges thereof aligned with each other, the contact pieces of the first memory card and the contact pieces of the second memory card have longitudinally overlapping parts and transversally overlapping parts as viewed from above.
