Abstract
Addressing circuit for a matrix display having shift registers formed by static memories and process for addressing with such a circuit. For a display with p columns, the circuit comprises p register points formed by static memories (M.sub.i), a first series of switches (C.sub.1) placed in front of the register points M.sub.k-1, k being an even number between 1 and p, a second series of switches (C.sub.2) placed in front of the register points M.sub.k and a transfer clock (13) producing a first signal (.phi..sub.1) controlling the first series of switches, in order to ensure the loading of a '1' signal into the register point (M.sub.1) and the transfer of the content of register point M.sub.k to register point M.sub.k+1, and a second signal (.phi..sub.2) controlling the second series of switches for ensuring the transfer of the content of register point M.sub.k-1 to register point M.sub.k.
