Data for Page N is input to Data Cache.
Data is transferred to the Page Buffer by the 15h command. During the transfer the Ready/Busy outputs Busy State (t
Data is programmed to the selected page while the data for page N + 1 is input to the Data Cache.
By the 15h command, the data in the Data Cache is transferred to the Page Buffer after the programming of page N is completed. The device output busy state from the 15h command
until the Data Cache becomes empty. The duration of this period depends on timing between the internal programming of page N and serial data input for Page N + 1 (t
Data for Page N + P is input to the Data Cache while the data of the Page N + P − 1 is being programmed.
The programming with Data Cache is terminated by the 10h command. When the device becomes Ready, it shows that the internal programming of the Page Ν + P is completed.
NOTE: Since the last page programming by the 10h command is initiated after the previous cache program, the tPROG during cache programming is given by the following;
