Title: Three dimensional memory
Inventor: NAKAGIRI NOBUYUKI
IPC: G02F1/13
Filed: 1992-02-07
Abstract: PURPOSE:To provide a three dimensional memory which dramatically increases the storage capacity and greatly reduces the time required for a retrieving. CONSTITUTION:A memory cell 1 consists of a memory into which a material whose optical characteristics vary in accordance with electrical voltages such as liquid crystal material, that is transparent under a normal condition but becomes less transparent when a voltage is applied, is enclosed and an empty memory. Then, n1Xn2 pieces of memory cells 1 are placed in accordance with the storage condition to make up a two dimensional memory cell 2. The top and the bottom of the cell 2 layer is sandwitched by transparent electrode sheets 3. A three dimensional memory cell 4 is made up with n3 pieces of layers of the cells 2. If a Kth layer memory is to be read, a voltage is applied between the Kth and a(K+1)th electrodes and a light from the corresponding address (x, y) of a light emitting element 5 is made incident on the three dimensional memory cell. By the variation of the optical characteristics of a memory cell (k, x, y) of the Kth layer, for example the presence or the absence of the enclosure of a liquid crystal, the light intensity is detected at the corresponding address (x, y) of a light receiving element 6 placed right behind a memory cell (n3, x, y) of a last layer. Thus, the recorded information of the address (x, y) of the memory cell of the Kth layer is read for example as information (1) or (0).

Title: Digital-to-analog converting circuit
Inventor: ASARI SHIGEATSU
IPC: H03M1/74
Filed: 1984-02-09
Abstract: PURPOSE:To simplify the conversion into a semiconductor and to improve easily the converting accuracy of a D/A converting circuit, by providing a constant current source and (n) stages of control circuits for differential current switching circuits of said current source to specify each constant current value together with addition circuits of each constant current and addition current loads. CONSTITUTION:A constant current source contains TRs Q13-Q16 and resistances R5-R8, and the current values I1-I4 are set at In=AX2<n-1> (A: constant) by those resistances R5-R8. Then TRs Q1-Q4 control the differential current switching circuit of the constant current circuit, and a current mirror circuit A adds the constant currents. Thus inputs D1-D4, output currents and voltages are shown in a table. Here I2=2I1, I3=4I1 and I4=8I1 are satisfied together with TRQ17=Q15, R9=R10 and R12=1/2R9 respectively. Then TRs Q1-Q4 are turned on and off when inputs D1-D4 are set at 0 and 1. Therefore a load current I5 produces a current output of an integer multiple and the output voltage V3 is equal to the output voltage of an integer multiple as shown in the table. As a result, the potentials of 16 stages are produced with 4 bits. The converting accuracy is decided by the accuracy of the resistances which decide each constant current value.
