    • A flash memory (10) includes a flash transistor array (12a, 12b, 12i), a wordline decoder (14), a bitline decoder (18), a sourceline decoder (22) and a read/write controller (26). The read/write controller (26) has a voltage terminal to receive an input voltage and a data terminal configured to sense a signal on a selected bitline and to generate an internal old amplifier and configured to compare the new data signal to the old data signal and to generate a comparator signal. A voltage generator is configured to selectively apply one of a read set of voltages to program a selected cell and an erase set of voltages to erase a selected cell. In a multistate embodiment, the read/write controller further includes a step counter configured to generate a plurality of step counts. The voltage generator is coupled to the step counter and configured to generate a wordline high voltage (WLHV) signal based on the step count. The WLHV signal is delivered to a selected multistate cell by the wordline decoder to read the contents of the selected multistate cell. Each step compares the old data and the new data in order to determine which memory cells to change. Advantages of the invention include increased flexibility of programming and erasing and improved memory longevity.
    • 闪速存储器(10)包括闪存晶体管阵列(12a,12b,12i),字线解码器(14),位线解码器(18),源线解码器(22)和读/写控制器(26)。 读/写控制器(26)具有用于接收输入电压的电压端子和被配置为感测选定位线上的信号并产生内部旧放大器并被配置为将新数据信号与旧数据信号进行比较的数据端 并产生比较器信号。 电压发生器被配置为选择性地施加读取的一组电压以编程所选择的单元和擦除电压组以擦除所选择的单元。 在多状态实施例中,读/写控制器还包括配置成产生多个步数的步数计数器。 电压发生器耦合到步进计数器并且被配置为基于步数产生字线高电压(WLHV)信号。 WLHV信号由字线解码器传送到选定的多状态单元,以读取所选择的多态单元的内容。 每个步骤都比较旧数据和新数据,以确定要更改的存储单元。 本发明的优点包括增加编程和擦除的灵活性并改善记忆寿命。
