Abstract: An asymmetric key cryptographic system is used to generate a cryptographic certificate for authenticating a memory module. This certificate is generated based on information, readable by the authenticator (e.g., host system), from at least one device on the memory module that is not read in order to obtain the certificate. For example, the certificate for authenticating a module may be stored in the nonvolatile memory of a serial presence detect device. The certificate itself, however, is based at least in part on information read from at least one other device on the memory module. Examples of this other device include a registering clock driver, DRAM device(s), and/or data buffer device(s). In an embodiment, the information read from a device (e.g., DRAM) may be based on one or more device fingerprint(s) derived from physical variations that occur naturally, and inevitably, during integrated circuit manufacturing.

Abstract: A memory system includes dynamic random-access memory (DRAM) components that include interconnected and redundant component data interfaces. The redundant interfaces facilitate memory interconnect topologies that accommodate considerably more DRAM components per memory channel than do traditional memory systems, and thus offer considerably more memory capacity per channel, without concomitant reductions in signaling speeds. Each DRAM component includes multiplexers that allow either of the data interfaces to write data to or read data from a common set of memory banks, and to selectively relay write and read data to and from other components, bypassing the local banks. Delay elements can impose selected read/write delays to align read and write transactions from and to disparate DRAM components.

Abstract: Methods and systems for chemical analysis. For instance, a device for chemical analysis of a sample includes a housing, an inlet, a pump, multiple membranes and at least one detector. The housing contains an interior chamber of the device. The inlet on the housing introduces the sample into the interior chamber. The pump is connected to the housing to form a partial vacuum in the interior chamber. The multiple membranes have different response times to different constituents of the sample. The multiple membranes include at least a first membrane and a second membrane. The multiple membranes have different response times to different constituents of the sample. The detector is for detecting the different constituents of the sample after interaction with the multiple membranes. In addition, a method for chemical analysis of a sample. A first step includes introducing a sample to multiple membranes having different response times to different constituents of the sample.

Abstract: Self-expandable, woven intravascular devices for use as stents (both straight and tapered), filters (both temporary and permanent) and occluders for insertion and implantation into a variety of anatomical structures. The devices may be formed from shape memory metals such as nitinol. The devices may also be formed from biodegradable materials. Delivery systems for the devices include two hollow tubes that operate coaxially. A device is secured to the tubes prior to the implantation and delivery of the device by securing one end of the device to the outside of the inner tube and by securing the other end of the device to the outside of the outer tube. The stents may be partially or completely covered by graft materials, but may also be bare. The devices may be formed from a single wire. The devices may be formed by either hand or machine weaving.
