    摘要: A protocol provides authentication of peripheral devices by a computing device to which the peripheral device connects. Computing devices include a verifier with a public key that authenticates multiple associated private keys. Private keys are embedded on peripheral devices. When the verifier is able to authenticate a connected peripheral, particular functionality is enabled that may not be enabled for peripherals that do not authenticate.

    摘要: A method and apparatus for producing a corrected bit stream from a random bit stream output by a random bit source. Sequential pairs of bits in the random bit stream are compared. If both bits in a pair of bits are identical, the output bits are discarded. If both bits in a pair of bits are different, one bit of the pair of bits is taken as the output bit.

    摘要: A method for monitoring the operations of a flash memory array divided into individually erasable blocks of memory in order to assure the integrity of data stored in the array in which each read or write operation is verified to detect an error which may have occurred in the operation including the steps of attempting at least one retry operation whenever an error occurs to determine whether the error is repeatable, marking the block to indicate valid data should be removed from the block if the error is found to be repeatable, removing the valid information from the block if the error is found to be repeatable, and removing a block with a repeatable error from operation.

    摘要: A memory system contains memory cells for storing multiple threshold levels to represent storage of "n" bits of data. The memory system includes an address buffer for generating a plurality of physical addresses such that each physical address uniquely identifies a memory location for "j" memory cells. In order to address a portion of the "n" bits identified by a single physical address, the address buffer generates a multi-level cell (MLC) address. The memory system also contains a switch control for permitting selection a multi-level cell (MLC) mode and a standard cell mode. A select circuit permits reading a single bit per cell when the memory operates in the standard cell mode, and permits reading multiple bits of data per memory cell when the memory operates in the multi-level cell mode. The addressing scheme of the present invention maintains address coherency by exhibiting a n:1 correspondence between memory locations and the physical addresses when operating in the MLC mode, and by exhibiting a 1:1 correspondence between memory locations and the physical addresses when operating in the standard cell mode.

    摘要: A method for insuring that an erase operation practiced on a block of flash EEPROM transistors is carried out reliably including the steps of: writing whenever the erasure of a block of the flash EEPROM array is to commence to a position in the array to indicate that an erasure of the block has commenced, writing whenever the erasure of a block of the flash EEPROM array is complete to the position in the array to indicate that an erasure of the block has been completed, testing to determine any positions in the array which indicate that an erasure of a block has commenced but not been completed upon applying power to the flash EEPROM array, and reinitiating an erase if any positions in the array exist which indicate that an erasure of a block has commenced but not been completed.

    摘要: A method for writing data to an entry in a portion of a flash EEPROM memory array during a period in which that portion of the array is being erased and writing is prohibited. The method includes writing the data to a new entry position apart from the portion of the array which is being erased along with a revision number which is greater than the revision number of the original data in the original portion of the array, writing of the busy condition of the original entry to a temporary storage position apart from the portion of the array which is being erased, and invalidating entries listed in the temporary storage position when the erase operation is concluded.
