Abstract
A column redundancy architecture for arrayed parallel processor devices is disclosed. In particular, daisy chained communication between processing elements is preserved after defective memory columns and their associated processing elements are disabled, by setting a bypass circuit within the processing element to be disabled. An address remapping circuit ensures that spare memory columns and associated processing elements replacing the defective memory columns and processing elements can be addressed in a linear column order. The column redundancy architecture is flexible as it permits replacement of arbitrary numbers of series adjacent processing elements as well as non adjacent processing elements with a minimal impact on device performance.
