  • Patent number: 11954333
    Abstract: A data storage device and method for detecting malware on a data storage device. The device includes a non-volatile storage medium configured to store at least one file system control block and user data block(s) to store user data. The file system control block comprises at least one reference data structure. The data storage device further comprises a buffer to temporarily store user data. The data storage device further comprises a controller to scan each write command in the user data to be transferred for protocol commands or malicious data. The controller also stops the data transfer of user data from the buffer to the non-volatile storage medium if at least one of protocol commands or malicious data is detected in at least one write command.
    Type: Grant

  • Patent number: 11360923
    Abstract: A multi-memory SD card includes an enclosure having the outer dimensions of a standard SD card. Two separate SiP SD packages are provided along with two separate sets of electrical contacts each according to the SD standard to provide, in a single SD card bundle, the functions and performance of two SD cards. The SiP packages may both be full size SD format, or one may be a micro- or nano- SD card. The first and second SiP SD packages has the same or different capacity and/or speed, and the micro- or nano- SiP package is permanent or removable. An onboard battery and/or PCB may also be housed in the enclosure for configuring WiFi/redundant array of independent disks (RAID) or backup.
