Patent number: 10978169Abstract: A method for ensuring that a memory array such as a ferroelectric memory array is properly electrically connected. The method may be performed, for example, prior to a read or write cycle, during functional testing of the memory array, etc. In one implementation, the memory array is read and the data set including a data bit from each cell is stored in a register. A solid logic 0's pattern is written into the memory array, and each cell is read. If no cell returns a logic 1, it is determined that the memory array is properly connected and the register data values are written to the memory array. If one or more cells returns a logic 1, it is determined that the memory array is improperly connected, the register data values are written to the memory array, and the memory array is removed and reinstalled.Type: GrantFiled: March 17, 2017Date of Patent: April 13, 2021Assignee: XEROX CORPORATIONInventors: Markus Rudolf Silvestri, Kamran Uz Zaman, Christopher P. Caporale, Jimmy E. Kelly, John M. Scharr, Alberto Rodriguez, Dennis J. Prosser
