摘要： In a circuit that reduces power consumption in an array system of memory cells accessible in parallel, a local evaluation circuit is connected to a memory cell and a global bit line of the array system of memory cells. A selection circuitry splits the global bit line into an upper part and a lower part of the global bit line. The selection circuitry is adapted to receive an early set prediction signal and to connect the upper part of the global bit line to the lower part of the global bit line based on the early set prediction signal. The early set prediction signal indicates whether a set of memory cells, which include the memory cell, is being read. The circuit also includes a N:1 multiplexer connected to the lower part of the global bit line to receive the lower part of the global bit line as input.

摘要： A memory array can be arranged with header devices to reduce leakage. The header devices are coupled with a decoder to receive at least a first portion of a memory address indication and are coupled to receive current from a power supply. Each of header devices is adapted to provide power from the power supply to a set of the wordline drivers corresponding to a bank indicated with the first portion of the memory address indication. Each of the logic devices is coupled to receive at least a second portion of the memory address indication from a decoder. Each of the logic devices is coupled to activate the wordline drivers coupled with those of the wordlines indicated with the second portion of the memory address indication.

摘要： A method for testing memory elements of an integrated circuit with an array built in self test (ABIST) comprises providing an ABIST interface to interface between an ABIST engine and a plurality of latches of a memory element under test, providing a multiplex (MUX) stage adjacent a scan input port of each latch, providing functional signal inputs to a data input port of the latches, setting the latches to an ABIST mode by activating an ABIST enable signal and delivering the ABIST enable signal to each of the latches, generating a plurality of ABIST test signals with the ABIST engine, applying the ABIST test signals in parallel to the scan input ports of the latches, determining whether one or more test patterns have been executed, and setting the latches to a normal run mode by deactivating the ABIST enable signal.

摘要： A method for bypassing a memory array in a circuit having a global bit line, a test port configured to output a logic test, a memory portion connected to the global bit line via a word line, a header device being connected to the global bit line via a pre-charge signal, the header device being configured to recharge the global bit line. A gating signal is sent to a gating device connected to the header device. The gating device is switched to a test mode upon receipt of the gating signal. The bypass data signal is sent to an evaluating device connected to the gating device, the evaluating device being configured to output a logic test. The logic test is output through the test port upon receipt of bypass data signal.
