Abstract
A generic data scrambler is provided for a built-in self-test (BIST) engine of a stacked memory device. The stacked memory device includes a memory stack of one or more memory layers; and a system element that is coupled with the memory stack. The system element includes a memory controller for the memory stack; a BIST circuit for testing of the memory stack; and a generic data scrambler for scrambling of data according to a data scrambling algorithm for the memory stack. The generic data scrambler includes a programmable lookup table to hold data factors for each possible outcome of the data scrambling algorithm, and the programmable lookup table is to generate a set of data factors based on addresses of data for testing of the memory stack.
