摘要： A CMOS data register includes a master stage and a slave stage. The master stage is formed of first transfer gates and first storage devices. The slave stage is formed of second transfer gates, second storage devices and third transfer gates. The transfer gates and storage devices are formed of MOS transistors of one conductivity which decreases layout complexity and reduces the amount of chip area required. The data register is formed of a fewer number of transistor components, thereby reducing the loading on the clock signals.

摘要： An array arrangement for EEPROMS in which each memory cell has two transistors. Selection is simplified whereby in selecting a cell all of the cells in the selected row are connected to one terminal of the writing circuit and all the cells in the selected column are connected to the other terminal. This selection process prevents any cell from being written into except the cell at the intersection of the selected row and the selected column.
