Title: Data writing method for a semiconductor memory
Inventor: TAKESHITA KAZUHIRO
IPC: G11C16/02
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce the number of re-try writing operations and a data writing time by varying widths of a fundamental pulse and a re-try pulse at writing in accordance with the number of re-try generations. SOLUTION: At data writing for a flash EEPROM 21, after setting a width of an initial writing pulse and providing the writing pulse via a mode setting section 23, a readout mode is set by the mode setting section 23 and an address data set by an address setting section 25 is read out, so that a control section 26 compares the writing date with the readout data. When a re-try generates, the width of the writing pulse is set at a different value, and the similar operations are repeated until both data coincide with each other. Then, a writing address is compared with a stop address, and a width of a fundamental pulse is varied depending on whether or not the re-try has generated. An address to be written is set as a next address, and the re-try generating condition is reset. The above operations are repeated until the writing address goes beyond the stop address.

Abstract: PURPOSE:To obtain a fuzzy controller which obtains the flexible conclusion accordant with the importance and has a high degree of expressing ability for the heuristic knowledge by setting previously the importance for each rule to be applied and multiplying the conclusion of each rule by the importance to output them when an output fuzzy set is obtained. CONSTITUTION:The 1st and 2nd inputs are inputted to the function generators 11 and 12 for acquisition of the grades of membership functions respectively.

Plural sets of such circuits are prepared for acquisition of a normal controller. In this method, the multipliers 112 - 1N2 and the rule importance degrees 113 - 1N3 are newly set between the lower value priority devices 110 - 1N0 and a higher value priority device 100. Thus the importance degrees are multiplied with use of the multipliers including newly the fuzzy assemblies obtained by the priority devices. Then an output omega0 is outputted from the device 100 via a centroid computing element 101.

Temperature of refrigerant flowing through a channel 21a is constant at, all times and the temperature difference between the refrigerant and the air is large on time air flow-in side and the state is reversed on the flow-out side. Since the heating tube 21 has a larger quantity of exchanging heat on the air flow-in side, refrigerant begin to be condensed quicker and the liquid phase s strengthened for the refrigerant lowing on the air flow-in side whereas gas phase is strengthened on the air flow-out side. The strong liquid phase and gas phase are fed together into a mixing chamber 22 and mixed and then arranged into substantrally uniform state before being distributed to respective channels 21a. According to the arrangement, difference of void rate between the flow-in side and the flow-out side is decreased thus decreasing pressure loss among respective channels 21a.
