Abstract
A semiconductor memory circuit is arranged with an ordinary crosspoint row-column array of dynamic capacitor memory storage cells. Word serial content addressing is enabled by adding a separate combinational logic device, only one such device for each entire column bit line, typically comprising a comparator feeding a NAND gate to which masking data can be supplied.
