摘要:
Systems and methods disclosed herein provide for selectively activating or deactivating one or more memory of a memory array, such that related data path logic of deactivated memory dies neither detects nor processes control signals or data signals for data operations. Examples of the systems and methods provided herein operate to detect a first enable signal at a memory die and detect a first data signal on input/output (I/O) receivers of the memory die. Responsive to detecting at least the first enable signal, a bit value encoded in the first data signal is latched to obtain a first bit pattern. A second bit pattern is obtained, and, based on a comparison of the first bit pattern to the second bit pattern, the I/O receivers of the memory die are activated.
