Title: Testing a digital memory
IPC: G11C29/02
Filed: 1975-12-19
Abstract: 1536857 Testing a digital memory PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Dec 1975 [23 Dec 1974] 52041/75 Heading G4A A method of testing a digital memory comprising 2<SP>N</SP> discrete randomly addressable storage positions for binary information and employing addresses containing N binary information elements which are initially arranged in accordance with a first order of significance, comprises filling the storage positions with first information, reading the storage positions during a first cycle in accordance with a first address sequence of successive addresses, filling the storage positions with the inverse of the first information, reading the storage positions during the first cycle in accordance with the reverse of the first address sequence, and repeating the sequence of reading-writing- reading-writing during a second cycle wherein the order of significance of the N binary information elements is modified. The results of reading each storage position is compared with its anticipated value and if a disparity occurs an error is signalled, the current test cycle then being terminated. Error signalling may be visual. The order of significance of the N binary information elements may be cyclically or otherwise permuted; in the case of cyclic permutation this is achieved by assigning during each test cycle a particular bit position of an address counter as having the lowest order of significance. The second cycle may subsequently be repeated N-2 times, each time a different binary information element having the lowest order of significance. The first information may consist of all 0's or all 1's. There may be a plurality of storage elements per storage position, a particular storage element being identified by a pointer for reading and writing. During each reading cycle it is then tested whether those storage elements prior to the pointer contain the inverse information to the anticipated values (as they have been overwritten by the inverse information) whereas those at and subsequent to the pointer contain the anticipated values. All the storage elements of a storage position, or storage elements of corresponding orders in all the storage positions, may be successively tested. It is stated that the method can detect errors due to stuck address bits or information bits, one- or two-sided couplings between pairs of address bits or pairs of information bits, one- or two-sided couplings between two rows, a row and a column, or two columns of the memory, and dynamic errors affecting, inter alia, the set-up and hold times of address and information signals. Detailed circuitry implementing the method in the case of a 64 k memory is shown and described (Figs. 4-6, not shown).

Abstract: 1,091,508. Field effect transistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 24, 1964 [Dec. 26, 1963], No. 52459/64. Heading H1K. In an insulated gate field effect transistor the source-drain current path consists of two superposed layers, the one nearest the gate electrode having a higher conductivity than the other and a thickness no greater than the Debye length, i.e. the depth to which electrical fields are effective to modulate the majority carrier density. The higher conductivity layer is so doped that the surface and volume traps are completely filled so that all field induced majority carriers are mobile. The superposed layers may be of the same semi-conductor, e.g. cadmium sulphide or lead sulphide of N or P type or of a different semi-conductor. In the embodiments, vapour deposited cadmium sulphide is used, the different conductivities being provided by varying the degree of non- stoichiometry, by varying the pressure of oxygen vapour in the deposition chamber or by introducing different amounts of a compensating impurity (e.g. a group Ib element for N-type material or a Va element for P-type material) either after or during formation of the layers as described in Specification 1,087,821. The electrodes of gold, and the insulating layer of silicon monoxide or calcium fluoride are also vapour deposited through masks as described in that Specification.

Abstract: 1363156 Generating pulse trains INTERNATIONAL COMPUTERS Ltd 31 Oct 1972 [25 Nov 1971] 54691/71 Heading G4H [Also in Division H4] Apparatus comprises means for moving a member at a variable velocity, e.g. in simple harmonic motion, and means responsive to the velocity of the member to generate a train of clock pulses, the time intervals between successive clock pulses in the train being varied to correspond to a succession of substantially equal increments of movement during the motion. As described, means for scanning a document, Fig. 1 (not shown), by means of a lens assembly (2) which directs an image of a portion of a document (15) on to an array of photodiodes (4) comprises an electrical vibrator (1) which causes the lens assembly to perform harmonic motion above the document, whereby characters may be scanned by the diode array. A coil 19 is attached to the shaft (17), (18) moved by the vibrator and is arranged between the poles of a permanent magnet (20) so that an A.C. signal is generated in the coil having a waveform corresponding to that of the velocity of motion. This signal is amplified at 6 and rectified at 7 so that only parts of the signal corresponding to scanning movements in a first sense are used. The signal is then passed to a controlled pulse generator 8 where it is used to charge a capacitor 10 connected between the base and drain of F.E.T. 12. Whenever the voltage at 10 reaches a certain level the F.E.T. conducts to emit a pulse to a distributer 9 and to discharge tha capacitor 10. The pulses are used to sample in the output from the diode array (4) and are thus timed to occur after equal increments of the document have been scanned.
