REMOVABLE MEMORY CARD TYPE DETECTION SYSTEMS AND METHODS

摘要

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.

主权项

1. A removable memory card receptacle for receiving removable memory cards, comprising:
a housing comprising a pin configured to operatively couple with a corresponding contact on an inserted removable memory card; and a control system operatively coupled to the pin of the housing, the control system configured to detect whether the corresponding contact is coupled to a pre-defined voltage.
