Patent number: 7597268Abstract: A plurality of flash (solid state) media coupled to a single form factor connector to provide a module, i.e., referred to as a SmartStack module, that can be coupled directly to a device with a SmartStack module controller. The SmartStack module does not include a controller and is controlled from the host side. The form factor connector would typically be a CompactFlash (CF) form factor or some other form factor used in a variety of devices. The SmartStack memory module in a preferred embodiment includes a write protect switch that prevents certain portions of the memory within the SmartStack module from being written to. In addition, a portion of the flash memory will be allocated to the secure area for storing information to implement various forms of security. Another portion of the flash memory is allocated to store optional biometric information such as a user's fingerprint or retinal scan information, etc.Type: GrantFiled: July 27, 2007Date of Patent: October 6, 2009Assignee: MCM Portfolio LLCInventors: Larry Lawson Jones, Sreenath Mambakkam, Arockiyaswamy Venkidu

Patent number: 7526675Abstract: A method and software program for recovering data from corrupted flash media. In one aspect, the method employs a low-level access scheme that enables data to be recovered when high-level interfaces, such as file systems, are damaged. The type of flash media is determined, and a corresponding access scheme is employed. Depending on the type of damage to the media, a physical-to-logical table may be built and employed to sequentially access the flash media in search of indicia from which selectable file-types can be identified, or the media may be accessed using normal operating system commands. Once the file indicia are found, the location of corresponding file data is identified, whereupon the file data are read and stored. The software program employs an application program interface (API) comprising one or more sets of pass-through commands to enable low-level access to the flash media and to build the physical-to-logical table.Type: GrantFiled: June 23, 2006Date of Patent: April 28, 2009Assignee: MCM Portfolio LLCInventors: Sreenath Mambakkam, Shanmugavelu Thiagaraian, Jothikumar Govindaraju

Publication number: 20080250174Abstract: A flash-memory-card reader reads and writes multiple types of flash-memory cards, including CompactFlash, and the smaller SmartMedia, MultiMediaCard, Secure Digital, and Memory Stick. A converter chip converts the different card signals for transfer to a host personal computer (PC). Serial-to-parallel data conversion is performed for the smaller card formats with serial data interfaces, but not for CompactFlash with a parallel-data interface. A single slot has a 50-pin connector for CompactFlash cards or passive adapters. The passive adapters have the CompactFlash form factor and a smaller connector fitting smaller flash cards. Passive adapters have no components but simply wire the smaller connector to the CompactFlash connector. A pin mapping allows card-type detection by sensing the LSB address pins of the CompactFlash interface. A larger CompactFlash reader has multiple slots for each card type. The reader is connected to the PC by a cable, or located within the PC chassis in a drive bay.Type: ApplicationFiled: June 13, 2008Publication date: October 9, 2008Applicant: MCM PORTFOLIO LLC.Inventors: Larry Lawson JONES, Sreenath MAMBAKKAM, Arockiyaswamy VENKIDU
