The documentation I have here suggests the precharge doesn't erase all of memory. Precharge copies from the sense amplifiers back into the current row. The erasure is a result of the sense amplifiers losing their contents faster than the memory cells, but even so only one of the 2^12 rows gets erased. -- Adrian Cox http://www.humboldt.co.uk/
