1. A method of implementing a secure communications device comprising:

  • receiving data at a first communications device from a second communications device;

    wherein said received data is designated as ephemeral data to be treated in accordance with a set of ephemeral parameters by said first communications device;

    in response to said designation, storing said ephemeral data in an ephemeral non-volatile memory device that is coupled to but separate from said first communications device;

    wherein said ephemeral data from said second communications device is not stored in any non-ephemeral non-volatile memory circuit contained within the first communications device;

    automatically erasing said ephemeral data from the second communications device based on said set of ephemeral parameters, including in response to any or all of;

    a) a read access;

    b) a time expiration;

    c) a predetermined event relating to said ephemeral non-volatile memory device;

    wherein said automatically erasing based on said read access effectuates an ephemeral treatment of said data by irreversibly destroying said data at a physical level and such after any first read access is made to such data, said data is unreadable and cannot be read again within the ephemeral non-volatile memory device;

    configuring a memory controller on the first communications device to implement said automatically erasing using at least two different types of memory read access operations, including;

         1) an integrated read/erase operation; and

         2) separate read/erase operations.
