    • Devices and methods are disclosed by which a smart card or UICC that is removably insertable into a wireless terminal will only allow operation in either a specific terminal or a specific set of terminals. A mechanism to restrict the set of terminals that a UICC will operate with based upon logic embedded in a memory within the UICC. The UICC receives specific information from the wireless terminal when the terminal is turned on. If the information received satisfies a plurality of rules or conditions stored within the UICC, the UICC functions normally and the terminal may be registered with the network. If the UICC is inserted in an unsupported terminal, the UICC will refuse to function normally. This provides a deterrent against UICC theft.
    • 公开了可移除地插入到无线终端中的智能卡或UICC的设备和方法将仅允许在特定终端或特定终端集合中进行操作。 一种基于嵌入在UICC内的存储器中的逻辑来限制UICC将运行的终端集的机制。 当终端打开时,UICC从无线终端接收特定信息。 如果接收到的信息满足存储在UICC内的多个规则或条件,则UICC正常工作,终端可以向网络注册。 如果UICC插入不支持的终端,则UICC将拒绝正常运行。 这为UICC盗窃提供了威慑力。

    • Methods, devices, and systems are disclosed, including those for a buffer having pre-driver circuitry that provide voltages to thin-gate dielectric transistors. One such buffer may include a primary pull-up pre-driver operably coupled to a primary pull-up transistor; a secondary pull-up pre-driver operably coupled to a secondary pull-up transistor; a primary pull-down pre-driver operably coupled to a primary pull-down transistor; and a secondary pull-down pre-driver operably coupled to a secondary pull-down transistor. The pre-drivers may provide a sufficiently low voltage to a gate of a transistor operably coupled thereto so as to sustain a gate dielectric integrity of the transistor, wherein at least one of the primary pull-up pre-driver, the secondary pull-up pre-driver, primary pull-down pre-driver, and the secondary pull-down pre-driver is configured to provide a voltage greater than or equal to a ground voltage and less than or equal to a supply voltage.

    • Circuits, memories, and methods for latching a write command and later provided write data including write command and write data timing circuits. One such timing circuit includes internal write command latch to latch an internal write command in response to write command latch signal. The internal write command latch releases the latched write command in response to the write command latch signal after a latency delay. The timing circuit further includes a write leveling flip-flop (FF) circuit and a write data register. One such method includes generating and latching an internal write command. The latched internal write command is released after a latency delay responsive to the memory clock signal. The internal write command is propagated over an internal write command path. Write data is captured and internal write command latched in response to a write clock signal. The captured write data is released to be written to memory.
    • 用于锁存写命令的电路,存储器和方法,并且稍后提供包括写命令和写数据定时电路的写数据。 一个这样的定时电路包括内部写入命令锁存器,以响应写入命令锁存信号来锁存内部写入命令。 在延迟延迟之后,内部写命令锁存器响应于写命令锁存信号释放锁存的写命令。 定时电路还包括写平均触发器(FF)电路和写数据寄存器。 一种这样的方法包括产生和锁定内部写命令。 锁存的内部写入命令在响应于存储器时钟信号的延迟延迟之后被释放。 内部写入命令通过内部写命令路径进行传播。 写数据被捕获,并且内部写命令响应于写时钟信号而被锁存。 捕获的写入数据被释放以写入存储器。
