Serial access integrated circuit memory

Abstract

An integrated circuit serial access type memory, notably in EEPROM technology, includes a data input (DI) and a data output (DO), a defined memory plane (MM) organized in memory words, as well as a set (LAT) of column registers, one such register being associated with at least one memory word of the memory. The memory includes a writing circuit and/or a reading circuit. The writing circuit operates, during an operation for writing a binary word in a given memory word (M -M ), for loading the binary data of the binary word received in series at the data input (DI) directly into respective storage and switching latches (HV -HV ) of the column register (R ) associated with the memory word (M -M ). The reading circuit operates, during an operation for reading a binary word in a memory word, for reading successively the binary data stored in the memory cells of the memory word and for delivering directly, in serial form, each binary data read to the data output (DO) of the memory.
