(Continued)
A sector is typically erased and verified in 1.0 second. (If already completely preprogrammed.)
The device also features a sector erase architecture. The sector mode allows each sector to be erased and
reprogrammed without affecting other sectors. The MBM29LV652UE is erased when shipped from the factory.
Internally generated and regulated voltages are provided for the program and erase operations. A low VCC
detector automatically inhibits write operations on the loss of power. The end of program or erase is detected
by Data Polling of DQ7, by the Toggle Bit feature on DQ6. Once the end of a program or erase cycle has been
completed, the devices internally reset to the read mode.
The devices electrically erase all bits within a sector simultaneously via Fowler-Nordhiem tunneling. The words
are programmed one word at a time using the EPROM programming mechanism of hot electron injection.
