摘要:
A system that includes a controller for enabling an enumeration operation. The enumeration operation is performed by a controller (110) and logic elements (120) in a system, such that each logic element in the system assigns itself a unique identifier. Each logic element can then be controlled by another source or have a means to communicate with other logic elements in the system. The unique identifier enables greater system flexibility, thereby reducing cost and improving efficiency.

The present invention relates to a method and circuit for selectively repairing an embedded memory module having memory elements in an integrated circuit chip. The method includes performing a plurality of tests on the embedded memory module under operating conditions to identify a plurality of non-operational memory elements in the embedded memory module and, in response to identifying the non-operational memory elements, generating a plurality of corresponding repair solutions. The method further includes storing the plurality of corresponding repair solutions in a non-volatile storage element and determining from a mask a subset of the plurality of repair solutions that should be restored.

Processing engines (PE's) disposed on the substrate. Each processing engine includes a measurement and storage unit, and a PE controller coupled to each of the processing engines. The processing engines perform self-tests and store the results of the self-tests in the measurement and storage unit. The PE controller reads the results and selects a sub-set of processing engines based on the results and an optimization algorithm.

A multi-port electronic memory has a write through capability. Control features for enabling a write through path to an output and subsequently disabling without causing data errors due to design and technology variations are provided. Control features are especially beneficial for use with compilable SRAM books.

A design structure comprising a differential fuse sensing system, which includes a fuse leg configured for introducing a sense current through an electrically programmable fuse (eFUSE) to be sensed, and a differential sense amplifier having a first input node coupled to the fuse leg and a second node coupled to a reference voltage. The fuse leg further includes a current supply device controlled by a variable reference current generator configured to generate an output signal therefrom such that the voltage on the first input node of the sense amplifier is equal to the voltage on the second input node of the sense amplifier whenever the resistance value of the eFUSE is equal to the resistance value of a programmable variable resistance device included within the variable reference current generator.

A method and system for determining minimum post production test time on an integrated circuit device to achieve optimal reliability of that device utilizing defect counts. The number of defective cells or active elements with defective cells (DEFECTS) on the integrated circuit device are counted and this count serves as a basis for determining the minimum test time. A higher number of DEFECTS results in longer post production testing in order to achieve optimum reliability of the integrated circuit device. The number of DEFECTS can be counted on a device internal to the integrated circuit device and made available to determine the minimum required test time. The number of DEFECTS can also be obtained external to the integrated circuit device by intercepting information routed to another device. Information provided internally and externally can also reveal the physical location of DEFECTS to further refine the minimum required test time.

An Array Built-In Self Test (ABIST) circuit places on-chip circuits such as memory arrays in a known state, then stops. In the alternative, the ABIST circuit may initialize to a particular subcycle within a pattern sequence, and repeatedly loop on the subcycle, or repeatedly loop on the entire pattern sequence.
