Abstract: Removable memory card discrimination systems and methods are disclosed. In particular, exemplary embodiments discriminate between secure digital (SD) cards and other removable memory cards that comply with the SD form factor, but support the Universal Flash Storage (UFS) protocol. That is, a host may have a receptacle that supports the SD card form factor and is configured to receive a device. In use, a removable memory card is inserted into the receptacle and, using an SD compliant interrogation signal, the host interrogates a common area on the card so inserted. The common area includes information related to capability descriptors of the card. An SD compliant card will respond with information such as capability descriptors about the SD protocol capabilities, while a UFS compliant card will respond with an indication that the card is UFS compliant. The host may then restart the communication with the card using the UFS protocol.

Abstract: Removable memory card type detection systems and methods are disclosed. In one aspect, a removable memory card is inserted into a receptacle of a host. The host determines a type of removable memory card based upon either electrical or physical properties of the removable memory card. In this manner, if the host detects that the removable memory card possesses certain electrical or physical properties associated with a microSD card, the host determines that the removable memory card is a microSD type card. If the host detects that the removable memory card possesses certain electrical or physical properties associated with a UFS card, the host determines that the removable memory card is a UFS type card. By determining the card type based on detection of certain electrical or physical properties, aspects disclosed herein are able to distinguish between UFS and microSD cards without requiring an additional pin or card initialization time.

Abstract: A method, an apparatus, and a computer program product for communication are provided. The apparatus aggregates data sets as a function of an estimated characteristic of a next data set to arrive, and adaptively adjust the estimated characteristic based on a statistical measure of the estimated characteristic derived from a plurality of previously arrived data sets. The estimated characteristic may be an estimated next arrival time of the next data set, or an estimated size of the next data set.
