Web27 dec. 2016 · 因Flash工艺的流行，现在很多商人和不够严谨的技术人员将程序存储器称为Flash，对于那些仅采用传统EEPROM工艺的MCU而言，他们不求甚解，故而错误的将EEPROM程序存储器称为“ 模拟Flash”，根本的原因是他们未理解Flash只是一种存储器结构而非存储器的用途，错误的前提自然导致错误的结论。 WebFLASH VS. EEPROM Both the high-endurance Flash and the regular Flash memory arrays differ from a data EEPROM module in two important ways: a) Data must be manually erased before a write and this can be performed only in blocks (referred to as rows) of a fixed size determined by the Flash array inner design. b) Writing to Flash stalls the MCU ... WebCompared to EEPROM, Flash memories have higher density, which allow larger memory arrays (sectors) implemented on-chip. Flash erase and write cycles are performed by applying time-controlled voltages to each cell. In the erase condition, each cell (bit) reads logical 1.
