US Patent Number: US8327051B2

Title: Portable handheld memory card and methods for use therewith

Current Assignee: Palisade Technologies LLP (as of August 15, 2024)

Original Assignee: SanDisk Technologies LLC

Inventor: Myeong Joon Kang

Abstract:
A portable handheld memory card is described, featuring a Universal Serial Bus (USB) port, USB controller circuitry, an input/output (I/O) port, memory, and decompression circuitry for compressed data. The card's housing exposes both the USB and I/O ports, which are positioned to allow insertion in the same direction regardless of whether the host device uses a USB or I/O port. The patent also describes embodiments with decryption circuitry for encrypted data, a power management unit, a host interface module, and circuitry to manage memory read/write operations. The I/O port may be a Secure Digital (SD) port, and the memory can be Flash memory.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Portable Handheld Memory Card):
  This claim describes a portable memory card that has two distinct sets of electrical contacts on the same end: one for a Universal Serial Bus (USB) connection and another for a general Input/Output (I/O) connection. The card contains USB control circuitry connected to its USB pins, and I/O control circuitry connected to its I/O pins. It also has internal memory accessible via both ports, all housed within a casing that exposes these ports. A key feature is that the USB and I/O ports are arranged such that the card can be inserted into a host device in the same orientation, whether the host supports the USB port or the I/O port. Furthermore, if the I/O port is connected to a host, at least one pin of the USB port is not connected, and vice versa.

• Independent Claim 9 (Method for Data Handling with Memory Card - Type 1):
  This claim outlines a method performed by a portable memory card (as described in Claim 1) that involves managing compressed data. The method includes reading compressed data from the card's memory, decompressing it into uncompressed data, and then transmitting this decompressed data through the I/O port. Separately, the method also covers taking the original compressed data, converting it into a format suitable for the USB port, and transmitting that converted data through the USB port.

• Independent Claim 16 (Method for Data Handling with Memory Card - Type 2):
  This claim describes another method for a portable memory card (as described in Claim 1), focusing on flexible data transmission. The method involves reading data from the memory, then determining whether this data should be sent out through the USB port or the I/O port. Finally, the data is transmitted to a host device through the chosen port.

Uncertainty Regarding CAFC Dockets:
As of April 26, 2026, searches of CAFC 2026 dockets did not return any specific cases directly involving US8327051B2. The provided patent information indicates an Inter Partes Review (IPR) case (IPR2025-01008) was filed but "Not Instituted - Procedural," and a US case was filed in the Texas Western District Court, but these are not CAFC proceedings.
