Abstract: A method of testing non-volatile memory cells formed on a die includes erasing the memory cells and performing a first read operation to determine a lowest read current RC1 for the memory cells and a first number N1 of the memory cells having the lowest read current RC1. A second read operation is performed to determine a second number N2 of the memory cells having a read current not exceeding a target read current RC2. The target read current RC2 is equal to the lowest read current RC1 plus a predetermined current value. The die is determined to be acceptable if the second number N2 is determined to exceed the first number N1 plus a predetermined number. The die is determined to be defective if the second number N2 is determined not to exceed the first number N1 plus the predetermined number.

Abstract: A mobile communication device. The device comprises a cellular radio transceiver, a processor, a memory, and a custom application launcher stored in the memory. When executed by the processor, the custom application launcher periodically sends a message to an application server, wherein the message informs the application server that the custom application launcher is installed on the mobile communication device and, responsive to initiation of a process of removing the custom application launcher, sends a removal message to the application server, wherein the removal message informs the application server that the custom application launcher is being removed from the mobile communication device.

Abstract: A subscriber identity module (SIM) card. The SIM card comprises a processor, a memory, and an operation object. The memory stores, in part, the operation object, an integrated circuit card identifier (ICCID), an international mobile subscriber identity (IMSI), and an authentication key. When executed by the processor, the operation object causes a browser to be executed on a mobile communication device into which the SIM card is installed, provides a uniform resource locator (URL) to the browser, wherein the URL identifies a Web site, and causes the browser to send a request to the URL to download a custom application launcher and to install the custom application launcher on the mobile communication device.
