To provide a semiconductor memory device that can ensure adequate read margin by effectively utilizing a period for assigned CAS latency. In one embodiment, the pharmaceutical composition is administered parenterally, preferably by injection and intravenous drip. At least one or more piezoresistive pressure sensors are operably disposed proximate to the cavity. The message and the generated PAC may then be communicated to the mobile device, and the mobile device may be configured to utilize the shared secret to verify the PAC and authenticate the message.
