Memory Organization
The internal memory organization for the GSC24BC family is arranged differently for each of the densities. The
GSC24bc01, for instance, is internally organized as 16 pages of 8 bytes each and requires a 7-bit data word
address. The GSC24BC16, on the other hand, is organized as 128 pages of 16 bytes each with an 11-bit data
word address. The table below summarizes these differences.
