FLASH MEMORY
System Interface Using CE don’t-care.
For an easier system interface, CE may be inactive during the data-loading or sequential data-reading as shown below. The internal
528byte/264word page registers are utilized as seperate buffers for this operation and the system design gets more flexible. In addi-
tion, for voice or audio applications which use slow cycle time on the order of u-seconds, de-activating CE during the data-loading
and reading would provide significant savings in power consumption.
