Title: Non-volatile semiconductor memory device
Inventor: MATSUKAWA HISAHIRO
IPC: G11C17/00
Filed: 1985-05-01
Abstract: PURPOSE:To make it possible to shorten the writing time, by providing a capacitor for holding a writing voltage between a control gate and a source in a memory cell. CONSTITUTION:A capacitor C for holding writing voltage, which has the capacity of about 0.1pF is connected between a control gate terminal of an MOS transistor 18 and a source terminal S thereof. When data is written, a writing voltage of 15V is applied from a high voltage source, whose output impedance is, e.g., 10kOMEGA, to the terminal CG. Then, the capacitor C is charged to 15V in several ns. The ON state of the MOS transistor 18 is maintained by the voltage of the capacitor C. At this time, when, e.g., 10V is applied to a drain terminal D, hot carriers are generated, and writing is performed in 100mus-1ms. Therefore, the operating time of the high voltage source of 15V is only several ns for one memory cell. Thus, the data writing time can be shortened.

Abstract: PURPOSE:To prepare the dressing of SHIRAAE (white coating of food, i.e. vegetable dressed with white sesame, bean curd and white bean paste), wherein the gelation of the dressing and the separation of water from the dressing with heat is suppressed and the preservability can be improved by heating, by mixing bean curd refuse with soybean protein and water, or with bean curd. CONSTITUTION:The dressing of SHIRAAE is prepared by mixing bean curd refuse or a mixture of bean curd refuse, oils and fats, and water, with soybean protein and water, and/or bean curd. For example, 1pt. of dried bean curd refuse is mixed with 2pts. of refined soybean oil and 7pts. of water by a mixer, and the mixture is mixed with a desired amount of undrained bean curd (cotton-strained) by a mixer. The resultant mixture is mixed with sugar (9%), white bean paste (3%), salt (0.6%) and white sesame (proper amount) to obtain the objective dressing of SHIRAAE. The gelation of the dressing and the separation of water from the dressing by heating are reduced compared with conventional dressing, and its preservability can be improved by heating. It can be served after heating without further grinding, and accordingly, the heat-sterilization can be carried out without problems.
