Patent number: 11316687Abstract: Disclosed are apparatus and methods for programming a plurality of nonvolatile memory (NVM) devices. Each NVM device self-generates and stores a unique encryption key. Each NVM device concurrently receives an image from a multiple-device programming system to which all the NVM devices are communicatively coupled. Each NVM device encrypts the received image using such NVM device's unique encryption key to produce a unique encrypted image for each NVM device. Each NVM device stores its unique encrypted image within a nonvolatile memory of such NVM device. The unique encryption key can then be securely transferred to a host device for decrypting the image accessed from one of the NVM devices.Type: GrantFiled: December 13, 2019Date of Patent: April 26, 2022Assignee: Cypress Semiconductor CorporationInventors: Clifford Zitlaw, Markus Unseld, Sandeep Krishnegowda, Daisuke Nakata, Shinsuke Okada, Stephan Rosner

Publication number: 20100280817Abstract: A system, apparatus and method for emulating memory-mapped devices in the development of software where a device is mapped to protected memory space. When an instruction causing an attempted read or write to the protected space occurs, an exception or interrupt occurs, the instruction is analyzed and converted into a function call. The function call is sent to a device simulator for execution. The results of the function call are then used to update the registers of the processor and execution of application program will resume at a subsequent instruction.Type: ApplicationFiled: April 30, 2009Publication date: November 4, 2010Applicant: Spansion LLCInventor: Markus Unseld
