Apparatus and method for controlling data transfer between a serial data link interface (S3, S4) and memory banks (S1) in a semiconductor memory.
A flash memory device with multiple serial data links (S3, S4) and multiple memory banks (S1), where the links (S3, S4) are independent of the banks (S1), is disclosed.
The flash memory devices may be cascaded in a daisy-chain configuration using echo signal lines to serially communicate between memory devices. In addition, a virtual multiple link configuration is described wherein a single link (S2) is used to emulate multiple links (S3, S4).
Method of anonymized storage of personal data and method of managing access to these data.
The anonymization of the data is done by making independent, through the use of a chain of blocks, the identifiers of data sources and users on the one hand, and personal data on the other hand.
The personal data is stored at addresses indexed by their hashed values in a first database (115) and the identifiers are stored with their corresponding access profiles in a second database (145).
The link between these two independent databases is provided by cryptographic elements recorded in the register of the block chain.
