摘要： In a memory (100), a local data line pair (116, 118) is precharged to a first logic state and a global data line pair (101, 104) is precharged to a second logic state. A selected memory cell is coupled to the local data line pair (116, 118) to develop a differential local data line voltage. The differential local data line voltage is subsequently amplified to form an amplified differential local data line voltage. A selected one of the global data line pair (101, 104) is driven to the first logic state in response to the amplified differential local data line voltage to form a differential global data line voltage.

摘要： Methods and systems for configuring characteristics associated with at least one portion of a memory array comprising addressable units are provided. In one aspect, a method for controlling a power supply voltage for a memory array comprises detecting whether an error occurred in performing a read operation on an addressable unit of the memory array using a first power supply voltage coupled to the memory array. The method further comprises incrementing an error counter for tracking an error count associated with the memory array and switching the memory array to a second power supply voltage if the error count is equal to or exceeds an error threshold for the memory array. The method further comprises, based on at least one condition, switching the memory array to the first power supply voltage and resetting the error counter to an initial value.
