The ROM includes parallel rows of conductors oriented normal to parallel doped regions which form column conductors. The ROM is implemented with field-effect transistors and comprises two decoder fields and a data field. The transistors of the decoder fields serve to define open circuits between adjacent column conductors in accordance with binary input signals applied to the decoder fields. In the illustrative ROM, a first column conductor is connected to a return terminal of a power supply and a second column conductor is connected to a "pull-up" circuit. The illustrative circuit provides for the connection of power supply return connections to both ends of the one column conductor and provides for the connection of pull-up circuits to both ends of the second column conductor.

INTERLEAVED WORDLINE ARCHITECTURE

Номер: CA0002340985A1
Принадлежит:

A high-density folded bitline memory array architecture is disclosed. High memory cell packing density is achieved by dividing polysilicon wordlines into short individual segments in the folded bitline scheme. Each wordline segment forms the gate of one or two DRAM memory cell transistors, and each segment is connected to a metal wordline, or conductor having low resistivity. By eliminating spaces between the memory cells due to passing wordlines, a cell arrangement and density similar to open bitline schemes is achieved. Further packing is obtained by arranging two columns of memory cells parallel to each bitline, each column offset with the other by a predetermined pitch. Therefore, by increasing the number of memory cells connected to each complementary bitline pair, each bitline pair can be cut in half and connected to its own bitline sense amplifier to reduce the bitline capacitance. Hence the memory cell architecture of the present invention occupies less area, and operates with faster ...

Fly-over conductor segments in integrated circuits with successive load devices along a signal path

Номер: US20130051128A1

The propagation delay of a signal through multiple load devices coupled sequentially along a conductor is improved by separating a subset of the load devices that is more distant from the signal source, and coupling the more distant subset to the signal through a fly-over conductor that bypasses the subset that is nearer to the signal source. The technique is applicable to subsets of bit cells in a random access memory (SRAM) coupled to a given word line, or to word line decoder gates coupled sequentially to a strobe signal, as well as other circuits wherein load devices selectable as a group can be divided into subsets by proximity to the signal source. In an SRAM layout with multiple levels, different metal deposition layers carry the conductor legs between the load devices versus the fly-over conductor bypassing the nearer subset.
