Fast program commands
The M29W256GH/L offers a set of fast program commands to improve the programming
throughput:
See either
for a summary of the fast program commands.
After programming has started, bus read operations in the memory output the status register
content. Write to Buffer Program command can be suspended and then resumed by issuing
a Program Suspend command and a Program Resume command, respectively (see
Section 6.1.9: Program Suspend command
command).
Write to Buffer Program command set
The Write to Buffer Program command set makes use of the device's 32-word/64-byte write
buffer to speed up programming. 32 words/64 bytes can be loaded into the write buffer.
Each write buffer has the same A23-A5 addresses. The Write to Buffer Program command
dramatically reduces system programming time compared to the standard non-buffered
Program command. When issuing a Write to Buffer Program command, the VPP/WP pin
can be either held High, VIH, or raised to VPPH.
