According to one embodiment, in a memory card, a sealing portion houses the memory chip and the controller chip and includes a first main surface and a second main surface arranged on an opposite side of the first main surface. A first terminal group includes a plurality of electrode terminals arranged in a first direction inside the first main surface. A second terminal group includes a plurality of electrode terminals arranged in the first direction inside the first main surface. A conductive pattern is arranged between the first terminal group and the second terminal group in the first main surface. A conductive pattern has a longer dimension than that of the electrode terminal in the first terminal group. The conductive pattern has a longer dimension than that of the electrode terminal in the second terminal group. The conductive pattern is in a planar shape.

Systems and methods are disclosed for using a color changing surface to display a status of a storage device. In certain embodiments, a storage includes a display-less enclosure, non-volatile memory, memory configured to store firmware, and control circuitry. The control circuitry can be configured to determine an available space in the non-volatile memory, determine a first color corresponding to the available space based on a mapping of ranges of available space to corresponding colors, apply a voltage to the electrochromic material to change the color changing surface to the first color, and cease application of the voltage to the electrochromic material, wherein the color changing surface retains the first color after cessation of the voltage.

A card-type storage device includes a processing chip and a memory module. The processing chip is selectively operated in a data accessing mode or a data uploading mode. The memory module is electrically connected with the processing chip. A first data set generated by the medical device at a first time point and a second data set generated by the medical device at a second time point are stored in the memory module. In the data accessing mode, a first storage list is established by the processing chip according to the first data set, and the first storage list is updated as a second storage list according to the second data set. If the processing chip judges that the second data set satisfies a predetermined condition, the processing chip enters the data uploading mode.

Embodiments of the present disclosure provide a device, system, methods and components related to a modular card. Example components of the modular card include a thin rectangular rear plate, a thin rectangular front plate overlying the rear plate, a first plurality of fasteners fixed to the thin rectangular front plate, a second plurality of fasteners fixed to the thin rectangular rear plate, the second plurality of fasteners being configured to be removably engaged with the first plurality of fasteners; a magnetic strip, and/or an integrated circuit. In operation a user may remove and/or replace various components to customize the modular card. Some customizations include altering the accounts to which the modular card relates. In some example, the modular card may include components which relate to different accounts.

A memory card is provided with various pad layouts to prevent a data signal pad from contacting a power contact in a host during insertion and removal of the memory card. The memory card can have a form factor and features that accommodate a relatively-large memory with relatively-high performance and accompanying thermal conditions. An efficient card lock mechanism is also provided.

A data storage device includes a case and a connector housed within the case. The connector includes a first connection interface having a plurality of connection fingers and a second connection interface having a plurality of springs. The case is positionable within a data storage device port such that the data storage device is completely disposed within the data storage device port when used.

An electronic device including an electronic assembly and an enclosure. The electronics assembly including a host interface and a direct user input interface. The direct user input interface remains exposed when the device is connected to a host via the host interface. The enclosure, substantially in the form factor of a microSD device, forms the outer boundary of the electronic device, overmolded on the electronics assembly.

A USB flash drive, comprising a housing comprising internal walls defining a receiving space, at least one of the internal walls having an engagement component, a memory main body disposed in the receiving space and comprising a hook slot component, and a fastener disposed in the receiving space comprising a protrusion component and a hook component, the hook component engaged with the hook slot component of the memory main body, and the protrusion component engaged with the engagement component of the housing, thereby fastening the memory main body to the housing.

A memory device includes first and second parts. The first part includes a plug receiver configured for reception of a plug and a head coupled to the plug receiver. The second part includes a cap end and a dummy socket coupled to the cap end. The dummy socket includes a first portion insertible into the plug receiver and a second portion configured for reception of the head. The cap end is configured for placement thereon of a cap, which is disposable over the plug.
