... Auto Erase (chip & sector) and Auto Program - Automatically program and verify data at specified address GENERAL DESCRIPTION The MX28F640C3T 64-mega bit Flash memory organized as 4M words of 16 bits. The 1M word of data is arranged in eight 4Kword boot and parameter sectors, and 127 32Kword main sector which are individually erasable ...

... In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and program operations produces reliable cy- cling. The MX28F640C3T/B uses a 2.7V~3.6V VCC sup- ply to perform the High Reliability Erase and auto Pro- gram/Erase algorithms. The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process ...
