    摘要: A memory system having a selectable configuration for sense amplifiers is included. The memory system can include bit cells and a switch module coupled to the bit cell and to a first portion of a sense amplifier. The switch module can connect, disconnect or cross couple the bit cell to the sense amplifier based on a test for the input offset voltage of first portion of the sense amplifier. A similar configuration can be implemented by a second portion of the sense amplifier. The system can also include a programmer module to configure a setting of the switch module and can include a column select module to couple the bit cells to the sense amplifiers based on what column of bit cell is to be read. Other embodiments are also disclosed.

    摘要: Systems and methods are disclosed for measuring signals on an integrated circuit die. In one embodiment, a reference signal is distributed to die locations proximal to the signals to be measured. The reference signal is transmitted over transport paths coupling each of the signals to be measured to the die output. The signals to be measured are transmitted over their respective transport paths and measured at the die output. The relative delay between the signals can be calculated using the reference signal measurements.
