Write Operation Status
Definition
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.
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.
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.
Method of writing multiple words, up to the maximum size of the Write Buffer, in one
operation. Using Write Buffer Programming results in greater than eight times faster
programming time than by using single word at a time programming commands.
Allows the host system to determine the status of a program or erase operation by
reading several special purpose register bits.
