A Low-Power Double-Edge-Triggered Address Pointer Circuit for FIFO Memory Design

Abstract

This paper presents a novel design of address pointer for FIFO memory circuits. Advantages of the proposed design include: reduced capacitive load on the pointer clock path, the use of a true single-phase clock, and double- edge-triggering clock scheme. The circuit has low power consumption, is immune to circuit racing conditions and suitable for high-speed operations. Techniques to implement clock gating in pointer circuit design for further reducing power consumption are also discussed. The proposed circuit is implemented with a 65 nm CMOS technology and its performance is compared with previous pointer circuits.
