US Patent 7818538 Hashing and serial decoding techniques

A serial decoding technique may employ one or more circular shift register strings in which an input to an element of a shift register string may be gated by either an address input or the inverse of the address input. An output word line of the decoder may be driven by a respective shift register stage in the case of a single shift register string, or by a logical combination of shift register stages from respective shift register strings in the case of multiple shift register strings.
