Embedded Memory (P33)
Number of program or erase operations allowed in a partition
Simultaneous program or erase operations allowed in other partitions while a
partition in this region is in Program mode
Simultaneous program or erase operations allowed in other partitions while a
partition in this region is in Erase mode
Types of erase block regions in this Partition Region.
Number of device hardware-partition regions within the device.
bits 0–3 = number of simultaneous Program operations
bits 4–7 = number of simultaneous Erase operations
bits 0–3 = number of simultaneous Program operations
bits 4–7 = number of simultaneous Erase operations
bits 0–3 = number of simultaneous Program operations
bits 4–7 = number of simultaneous Erase operations
x = 0 = no erase blocking; the Partition Region erases in bulk
x = number of erase block regions w/ contiguous same-size
erase blocks. Symmetrically blocked partitions have one
blocking region. Partition size = (Type 1 blocks)x(Type 1
block sizes) + (Type 2 blocks)x(Type 2 block sizes) +…+
(Type n blocks)x(Type n block sizes)
x = 0: a single hardware partition device (no fields follow).
x specifies the number of device partition regions containing
one or more contiguous erase block regions.
