Title: Digital Data Storage System
IPC: G11C11/04
Filed: 1968-04-22
Abstract: 1,190,337. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 22 April, 1968 [1 May, 1967], No. 18860/68. Heading H3B. In a thin magnetic film storage matrix an extra sense line is provided coupled to a row of thin film elements so that during read out the sense amplifiers coupled to common drive/sense lines are strobed by a signal produced in response to an output from a sense amplifier coupled to the extra sense line. In the store of Fig. 1 word lines 108 to 114 coated with anisotropic thin film material are traversed by pairs of transmission lines 15, 16; 17, 18; and 19, 20, the intersection of a pair of lines with a word line defining a two core per bit location. Information is written into a bit position by energizing one of the word lines 108 to 114 and simultaneously applying an appropriately polarized digit signal to one of the pairs of digit lines. The digit or bit signal is supplied by bit drivers 10, 11, 12 each having three input terminals and in operation a bit cycle gate signal is applied to terminals 152, 155, 158 to condition the transistor drivers, Fig. 4 (not shown), and an appropriate data signal applied to terminals 150, 151; 153, 154; or 156 or 157. At the same time as control signals are applied to terminals 152, 155, 158 the,same signals are supplied through respective inverters 170, 171, 172 to switches 80, 81, 82 connected between the ends of the bit/sense lines and differential sense amplifiers 90, 91, 92. The inverted control signal thus opens the switches 80, 81, 82 to isolate the sense amplifiers before the drive signals, delayed by their passage through the transmission lines, reach the ends of the lines. In order to read information from the store a read or word current is passed through the appropriate word line 30 to 33, the signal induced in the pairs of bit lines being amplified in strobed sense amplifiers 90, 91, 92, the switches 80, 81, 82, Fig. 5 (not shown), being closed. The sense amplifiers are strobed by a pulse from a dynamic strobe generator comprising transmission lines 106, 107 and their associated storage areas where they cross the word lines. When a current is passed through one of the word lines a unipolar voltage is developed in the strips 106, 107 as well as the data strips and after amplification the pulse produced is used to strobe the sense amplifiers 90, 91, 92. The strobe and data signals, propagated along the transmission lines, arrive at the terminals of their respective sense amplifiers simultaneously irrespective of the selected word conductor position.

IPC: H01L21/288
Filed: 1957-06-18
Abstract: 838,400. Electrodeposition of metals. PHILCO CORPORATION. June 18, 1957 [June 18, 1956], No. 19156/57. Class 41. A method of electrolytically plating an electrically conductive or semi-conductive body comprises directing a jet of electrolyte solution containing in addition to conventional constituents ethylene-diamine-tetra-acetic acid or a salt thereof, and passing an electric current between the jet and the body. The method may be employed in the manufacture of transistors involving the provision of a pair of opposed, closely confronting potential barriers in a thin wafer of semi-conductive material. The base wafer may first be provided with closely-spaced parallel depressions on the opposite faces by jet etching and then metal dots providing the potential barriers may be applied in the depressions by jet plating. The same electrolytic solution may be employed in jet plating as in jet etching. Suitable electrolytes are sulphates, chlorides or nitrates of metals to be deposited. The metal deposited by plating may be indium or gallium. By including in the electrolyte ethylene-diamine tetra-acetic acid or a salt thereof the current may be reduced below that normally.employed in jet plating to provide a metal deposit having a cross-sectional area smaller than that of the jet orifice employed. By means of the invention the same jet system may be used during plating as during etching and only a reversal of the flow of current is necessary to discontinue etching and initiate plating. Specified materials, of which the wafer may be formed, are germanium, silicon, magnesium oxide, lead sulphide, also tellurides, antimonides and arsenides. Salts of ethylene-diamine-tetra-acetic acid which may be used range from mono salts to tetra salts; salts of sodium, potassium, lithium, calcium, magnesium and ammonium are specified. Tartaric acid, or sulphonated hydrocarbons may also be present. As shown, Fig. 1 represents a view of jet etching wherein electrolyte 2 flows from jet orifices 3 and 4 and depressions are etched in base wafer 1. Fig. 2 represents a view of jet plating wherein metal deposits 5 and 6 are plated on base wafer 1 in the depressions etched in accordance with Fig. 1 and employing the same electrolyte solution and jet mechanism, the flow of current only being reversed. Specifications 805,291 and 824,484 are referred to.
