256-Mbit J3 (x8/x16)

Table 29. Device Geometry Definition (Sheet 2 of 2)

Offset Length

Description

Number of erase block regions within device:

1. x = 0 means no erase blocking; the device erases in “bulk”

2Ch

1

2. x specifies the number of device or partition regions with one or

more contiguous same-size erase blocks

3. Symmetrically blocked partitions have one blocking region

4. Partition size = (total blocks) x (individual block size)

Erase Block Region 1 Information

bits 0–15 = y, y+1 = number of identical-size erase blocks

2Dh

4

bits 16–31 = z, region erase block(s) size are z x 256 bytes
