Numonyx Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)
Start
Setup
-Write 0xE8
- Block Address
Check Buffer Status
- Perform Read Operation
- Read Ready Status on signal SR.7
(Note 1)
SR.7 = 1 ?
Word Count
- Address = block address
- Data = word count minus 1
(Valid range = 0x00 to 0xFF)
Load Buffer
- Fill write buffer up to word count
- Address = within buffer range
- Data = User data
Confirm
-Write 0xD0
- Block address
Read Status Register(SR)
SR.7 = 1 ?
Full Status Register Check(if
desired)
End
No
Yes

Flow Charts
Notes:
1.
The device defaults to output SR data after the Buffered Programming Setup command (E8h) is issued. CE# or OE# must
be toggled to update Status Register. Don’t issue the Read SR command (70h), which would be interpreted by the internal
state machine as Buffer Word Count.
