Abstract: 1305833 Gas-cell memories INTERNATIONAL BUSINESS MACHINES CORP 25 June 1970 [30 June 1969] 30806/70 Heading G4C A gas cell memory system includes a gas panel comprising gas cells defined by the intersections of two sets of co-ordinate lines (e.g. rows and columns) disposed on opposite sides of the panel, each cell being capable of being operated in a first storage state in which a relatively low potential across the intersection defining the cell is required to ignite the cell, or a second storage state in which a relatively high potential is required for this, the state of a selected cell being read by applying the relatively low potential to one of the relevant intersecting lines and detecting any resultant current in the other. A storage-sustaining sinusoid is applied to all the column lines but its amplitude is reduced during reading. A column of bit positions is written by also applying a positive pulse to the relevant column line and a negative pulse to those row lines at which 1 is to be stored, during the positive portion of the sustain sinusoid so that the firing level is exceeded where 1 is to be stored. A column is erased similarly to writing all l's but the pulses are applied during the negative portion of the sinusoid. The sustain sinusoid by itself will momentarily ignite each cell in the 1 state twice each cycle, when a positive or negative sustain level (less than the firing level) is exceeded positively or negatively respectively. To read a column, a positive pulse is applied to the column line during the positive portion of the (reduced amplitude) sustain sinusoid so that the sustain level is exceeded in that column only so that those cells storing 1 in that column momentarily ignite to provide an output signal on the respective row lines. The gas panel may be as in Specification 1,285,219 (referred to).
