Figure 9. Selective (Random) Read

Endurance

The FM24C04B internally operates with a read and

restore mechanism. Therefore, endurance cycles are

applied for each read or write cycle. The memory

architecture is based on an array of rows and

columns. Each read or write access causes an

endurance cycle for an entire row. In the FM24C04B,

a row is 64 bits wide. Every 8-byte boundary marks

the beginning of a new row. Endurance can be

optimized by ensuring frequently accessed data is

located in different rows. Regardless, F-RAM read

and write endurance is effectively unlimited at the

1MHz two-wire speed. Even at 3000 accesses per

second to the same row, 10 years time will elapse

before 1 trillion endurance cycles occur.
