Figure 10. Memory Read

Endurance

Internally, a FRAM operates with a read and restore

mechanism

similar

to

a

DRAM.

Therefore,

endurance cycles are applied for each access: read or

write. The FRAM architecture is based on an array of

rows and columns. Each access causes a cycle for an

entire row. Therefore, data locations targeted for

substantially differing numbers of cycles should not

be located within the same row. In the FM25640,

there are 2048 rows each 32 bits wide. Each 4 bytes

in the address mark the beginning of a new row.
