    Abstract: An integrated memory system with a spiral cache responds to requests for values at a first external interface coupled to a particular storage location in the cache in a time period determined by the proximity of the requested values to the particular storage location. The cache supports multiple outstanding in-flight requests directed to the same address using an issue table that tracks multiple outstanding requests and control logic that applies the multiple requests to the same address in the order received by the cache memory. The cache also includes a backing store request table that tracks push-back write operations issued from the cache memory when the cache memory is full and a new value is provided from the external interface, and the control logic to prevent multiple copies of the same value from being loaded into the cache or a copy being loaded before a pending push-back has been completed.

    Abstract translation: 具有螺旋高速缓存的集成存储器系统在由所请求的值与特定存储位置的接近度确定的时间段内响应耦合到高速缓存中的特定存储位置的第一外部接口处的值的请求。 高速缓存支持使用跟踪多个未完成请求的问题表和针对由高速缓冲存储器接收的顺序将多个请求应用于相同地址的控制逻辑的针对同一地址的多个未完成的飞行中请求。 高速缓存还包括后备存储请求表，其在高速缓冲存储器已满并且从外部接口提供新值时跟踪从缓存存储器发出的推回写入操作，以及用于防止相同值的多个副本的控制逻辑 在加载到缓存或正在加载的副本之前，等待推送已经完成。

    Abstract: A method, system and computer program product for generating device fingerprints and authenticating devices uses initial states of internal storage cells after each of a number multiple power cycles for each of a number of device temperatures to generate a device fingerprint. The device fingerprint may include pairs of expected values for each of the internal storage cells and a corresponding probability that the storage cell will assume the expected value. Storage cells that have expected values varying over the multiple temperatures may be excluded from the fingerprint. A device is authenticated by a similarity algorithm that uses a match of the expected values from a known fingerprint with power-up values from an unknown device, weighting the comparisons by the probability for each cell to compute a similarity measure.
