Abstract
The programming method includes the following steps: sequentially receiving a plurality of data words; temporarily storing each data word after its reception; and simultaneously writing in parallel the plurality of stored data words in a memory array. After reception and temporary storage of each data word, the memory increments an address counter and sends a 'ready' signal. Upon reception of each new data word, the memory verifies whether the address associated thereto is in the same sector as the initial data word and whether n data words have already been stored. If the sector is different, blind-programming step is terminated and the verifying is carried out; if the sector is the same but n data words have already been stored temporarily, the memory writes the temporarily stored words in the memory array, updates the address counter, and then sends the 'ready' signal.
