Patent GB-2002960-A (GB)
Title: Charge transfer memory apparatus
IPC: G11C27/04
Filed: 1978-08-17
Abstract: In a CTD, M(eg3) rows of charge transfer channels 11-13 each have identical sets of r(eg4) electrodes 31-34. In response to a first set of clocking voltages, N(eg4) charge packets, each of which is a sampled analog signal, are initially entered in parallel from an input shift register 45 vertically into the N successive stages contained in a first one 11 of the M horizontal rows, and concurrently the charge packets just previously stored in the first to (M-1)<th> rows, are transferred vertically for storage in the respectively like-numbered ones of the N stages, of the second to M<th> rows, respectively. This transfer is effected through channels 36c,36d connecting the (r-1)<th> electrode 33 of one row to the first electrode 31 of the next row. The entry and shifting continues in successive steps, until M such sequences, each containing N charge packets, are loaded in the array. Then, in response to a second set of clocking voltages applied to the sets of r electrodes 31-34, transfers are made horizontally in repeated steps, such that in each step the contents of the N<th> column are shifted out of the array and are read, those of the (N-1)<th> column are shifted into the N<th> column, etc. The CTD is suitable for integrated circuit fabrication and is usable for re-sorting the order of analog signal samples, such as in radar, colour television, image display, or medical electronics applications. <IMAGE>
