Abstract
In one embodiment, a portable handheld memory card may include a Universal Serial Bus (USB) port, USB controller circuitry, an input/output (I/O) port, a memory, and decompression circuitry configured to decompress compressed data stored in the memory. The memory card includes a housing storing the memory and exposing the USB port and the I/O port. The USB port and I/O port may be positioned to allow a same card-insertion direction irrespective of whether a host device comprises a mating USB port or a mating I/O port. In another embodiment, the memory card includes decryption circuitry to decrypt encrypted data stored in the memory, a power management unit, a host interface module, and circuitry configured to control read and write operations to the memory. The I/O port may include a Secure Digital port, and the memory may include Flash memory. Other embodiments are provided, and each of the embodiments described herein can be used alone or in combination with one another.
