Inf o rmation

Wraparound

Special burst read mode where the read address wraps or returns back to the lowest

address boundary in the selected range of words, after reading the last Byte or Word

in the range, e.g. for a 4 word range of 0 to 3, a read beginning at word 2 would read

words in the sequence 2, 3, 0, 1.

Write

Interchangeable term for a program/erase operation where the content of a register

and or memory location is being altered. The term write is often associated with writing

command cycles to enter or exit a particular mode of operation.

Write Buffer

Multi-word area in which multiple words may be programmed as a single operation. A

Write Buffer may be 16 to 32 words long and is located on a 16 or 32 word boundary

respectively.

Write Buffer Programming

Method of writing multiple words, up to the maximum size of the Write Buffer, in one

operation. Using Write Buffer Programming results in

≥ 8 times faster programming

time than by using single word at a time programming commands.

Write Operation Status

Allows the host system to determine the status of a program or erase operation by

reading several special purpose register bits.
