Filed: 1985-12-16
Abstract: PURPOSE:To substantially shorten the testing time by providing several types of test pattern accumulating ROM element arrays, writing stack information on the ROM elements in plural memory cell in a package and comparing stack information in the ROM elements with write information in the memory cells. CONSTITUTION:By setting a semiconductor memory in a test operational mode, a test is started. At testing, a write control signal TWE initially comes to a level 'H'. Through the selection of a ROM element word line 10, the stack information in the ROM elements is transmitted onto a bit line 4. By selecting an optional word line 3, the stack information is transmitted to the memory cell through a switching circuit 8. The word line is nonselective, and a desired test pattern is written in all memory cells in the memory cell array 1. The control signal TWE is assumed to be at said level 'L'. Any word line 3 is selected, and write information in the all memory cells connected to the word line 3 is amplified by a sense circuit train 7, whereby stack information on a bit line 4' is transmitted to a comparator circuit 15 through the bit line 4. Then the write information in all memory cells is compared with the stack information.

IPC: H04N1/04
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To improve the operating convenience of the user by forming an image to be a size most frequently used in general and transmitting the image as a facsimile signal. SOLUTION: An image size detection section 9 detects a size of an image to be transmitted. An image size comparison section 10 compares the size of the image to be sent with a preset paper size. When the size of the image is larger, an image reduction selection input section 11 displays a selection input menu as to whether or not the image to be sent is to be reduced. When the user selects reduction of the image, an image transmission control section 13 uses an image reduction section 12, to reduce the image to be a preset paper size and sends the reduced image as a facsimile signal. When the user selects 'non-reduction' of image, the image transmission control section 13 divides the image to the preset paper size and the resulting image is sent in a facsimile signal.
