Abstract: Provided is a method for transferring data from one clock domain within a synchronizer to another domain within the synchronizer. The method includes determining system clock parameters within the synchronizer and analyzing a first domain clock signal based upon the system clock parameters. Next, a second domain clock signal is analyzed based upon the first domain clock signal and the system clock parameters. A determination is made as to when to transfer data from a first clock domain to a second clock domain in accordance with the analysis of the first and second domain clock signals, and an enable signal is provided to affect the data transfer from the first domain to the second clock domain.

Abstract: A memory cell for reducing the cost and complexity of modifying a revision identifier (ID) or default register values associated with an integrated circuit (IC) chip, and a method for manufacturing the same. The cell, which may be termed a “Meta-Memory Cell” (MMCEL), is implemented on metal layers only and utilizes a dual parallel metal ladder structure that traverses and covers each metal and via layer from the bottom to the top of the metal layer structure of the chip. One of the metal ladders is connected to a power supply at the bottom metal layer, corresponding to a logic 1, and another metal ladder is connected to ground at the bottom metal layer, corresponding to a logic 0. The output of the MMCEL can thus be inverted at any metal or via layer and can be inverted as often as required. Significant cost savings are achieved because a revision ID or default register bits may be modified by altering only those metal layers where design changes are necessary.
