A method of managing priority in an electronic device, wherein the electronic device comprises a contact-less communication domain and a secure element domain, wherein the contact-less communication domain and the secure element domain are connected via a domain interface, and wherein the secure element domain comprises two or more interfaces. The method comprises: i) detecting (by the contact-less communication domain), a radio frequency (RF) field of an external device and, upon detecting said RF field or upon receiving a first command from the external device, ii) sending a priority request via the domain interface to the secure element domain; iii) receiving (by the secure element domain) the priority request and identifying whether the secure element domain is in a processing status, hereby iv) upon identifying that the secure element domain is not in a processing status, approving (by the secure element domain) the requested priority, and starting a transaction (by the contact-less communication domain) in a priority status; and v) upon identifying that the secure element domain is in a processing status, denying (by the secure element domain) the requested priority, and starting a mute status or remaining in a mute status (by the contact-less communication domain), such that the external device cannot detect the contact-less communication domain.

An electronic device and a method for managing an IC card with multiple SIM profiles is described. The electronic device comprises: i) an integrated circuit (IC) card domain, configured to store a first SIM profile and a second SIM profile, and ii) a communication domain coupled to the IC card domain via a physical interface. The IC card domain is configured to: a) generate a first logical interface on the physical interface and associate the first SIM profile with the first logical interface by providing a first logical interface identifier, and b) generate a second logical interface on the physical interface and associate the second SIM profile with the second logical interface by providing a second logical interface identifier. The communication domain is configured to: a) address the first SIM profile using the first logical interface identifier in parallel and independent of the second SIM profile and b) address the second SIM profile using the second logical interface identifier in parallel and independent of the first SIM profile.

There is described a method of managing memory in an electronic device, the method comprising creating a set of equally sized logical regions in a logical address space, each logical region comprising a plurality of consecutive logical addresses, and mapping a subset of consecutive logical addresses within each logical region to a set of physical addresses within a corresponding physical memory region, the subset of consecutive logical addresses comprising the first logical address within the logical region, said first logical address being mapped to a base address within the corresponding physical memory region. Furthermore, there is described a controller for managing memory in an electronic device and a method of determining a physical memory address in a physical memory region using such a controller.
