  • Publication number: 20240143791
    Abstract: The invention introduces an apparatus for detecting errors during data encryption. The apparatus includes a search circuitry and a substitution check circuitry. The key generation circuitry is arranged operably to convert a first value of one byte corresponding to a plaintext, an intermediate encryption result, or a round key into a second value of a K-bit according to an 8-to-K lookup table, where K is an integer ranging from 10 to 15 and the second value comprises (K minus 8) bits of a Hamming parity. The substitution check circuitry is arranged operably to employ check formulae corresponding to the 8-to-K lookup table to determine whether an error is occurred during a conversion of the first value of the one byte into the second value of the K-bit, and output an error signal when finding the error, where a total amount of the formulae is K minus 8.

  • Publication number: 20240107780
    Abstract: A system on chip (SoC) die package is attached to a redistribution structure of a semiconductor device package such that a top surface of the SoC die package is above a top surface of an adjacent memory die package. This may be achieved through the use of various attachment structures that increase the height of the SoC die package. After encapsulating the memory die package and the SoC die package in an encapsulation layer, the encapsulation layer is grinded down. The top surface of the SoC die package being above the top surface of the adjacent memory die package results in the top surface of the SoC die package being exposed through the encapsulation layer after the grinding operation. This enables heat to be dissipated through the top surface of the SoC die package.
