Control of access to data records

摘要

- After data from a record in a database is transmitted to a memory circuit (5), only write instructions are disabled (7) so that other processors may access the record (2) to read the data and use it. After processing of the data in the memory circuit (8), read instructions are also disabled (9) and the processed data is written to the record (10). This operation takes only a fraction of a second and immediately afterwards, the read/write controller is directed to enable both read and write instructions (12).
