A boot read only memory (ROM) chip unit can perform a secure boot routine based on various operations. A processor device comprises a boot ROM chip with processing circuitry on a system board configured to perform a system board power up according to a read operation in a one-time-programmable OTP memory/non-volatile memory (NVM). The OTP memory/NVM includes a spare area in a portion of the OTP/NVM that can receive a first sequence pattern. The processor determines whether a secure boot indication indicates a secure boot routine, and differentiates one or more read return content of the OTP memory/NVM between a wrongly read return content and a trusted read return content, in response to, or concurrent with, the secure boot indication indicating the secure boot routine.

There is provided a method for updating an internal memory on a semiconductor device from an external memory. The external memory is arranged in a plurality of data portions. The method comprises the steps of writing a first data portion from the external memory to the internal memory, processing the first data portion and, while the first data portion is being processed, once a selected data item is processed, starting to write a second data portion from the external memory to the internal memory. The method may be applied to the processing of software by an embedded processor on a semiconductor device. There is also provided a semiconductor device and a hardware module for the semiconductor device.
