... The unique cell architecture of the W29C020 results in fast write (erase/program) PP operations with extremely low current consumption compared to other comparable 5-volt flash memory products. The device can also be written (erased and programmed) by using standard EPROM programmers. FEATURES Single 5-volt write (erase and program) ...

... In the internal write cycle, all data in the page buffers, i.e., 128 bytes of data, are written simultaneously into the memory array. Before the completion of the internal write cycle, the host is free to perform other tasks such as fetching data from other locations in the system to prepare to write the next page ...

... There are two boot blocks (8K bytes each) in this device, which can be used to store boot code. One of them is located in the first 8K bytes and the other is located in the last 8K bytes of the memory. The first 8K or last 8K of the memory can be set as a boot block by using a seven-byte command sequence ...
