Title: Shift register
IPC: G11C19/18
Filed: 1971-01-14
Abstract: 1322851 Shift registers INTERNATIONAL BUSINESS MACHINES CORP 14 Jan 1971 [28 Jan 1970] 1790/71 Heading G4C A shift register comprises a plurality of cells #1,#2 each comprising a group of sub-cells, means for applying respective clock phases # 1 -# 4  to the sub-cells in each group, the number of sub-cells being n, where n is at least 3, and the number of bits of data capable of being stored in a cell being n-1, the clock phases being applied in inverse order (# 4 -# 1 ) to the order of the sub-cells of each group (e.g. l 1 -l 4 ). In the prior art (Fig. 1, not shown) each cell comprised two sub-cells which could hold one bit between them at a time. The present arrangement has four sub-cells which hold 3 bits between them at one time, thus increasing the bit storage capacity. The clock phases are energized in the order # 1 -# 4 , thus in the first cycle bit D 1  is gated to sub-cell 1 1  by phase # 4 . In the second cycle D 1  is gated to sub-cell 1 2  by phase 93 and D 2  is gated to sub-cell 1 1  by phase # 4 , and by the end of the fourth cycle bit D 1  is in sub-cell 1 4  and passes to sub-cell 2 1  of the next cell. By virtue of the phase order three bits can be stored in each cell at one time. Each sub-cell (Fig. 3, not shown) comprises two N or P type FET's and two capcitors. An input data bit turns the first FET on and charges a first capacitor while the phase # turns the second FET on and charges a second parasitic output capacitor. Each cell is formed as part of an integrated semi-conductor chip (Fig. 5, not shown).
