256Mb/512Mb/1Gb SEMPER™ Flash

HYPERBUS™ interface, 1.8V/3.0V

Address space maps

The address space for the SEMPER™ Flash family contains addressing for the main memory array, address space

overlays (ASO), manufacturer ID, device ID, unique ID, Serial Flash Discoverable Parameters (SFDP), SSR, and

registers.

SEMPER™ Flash memory array

The main flash array is divided into units called physical sectors.

The HL-T/HS-T family sector architecture supports the following options:

• 256Mb, 512Mb, 1Gb supports 256KB Uniform sector options

• 256Mb, 512Mb, 1Gb Hybrid sector options

- Configuration 1 - Physical set of thirty-two 4KB sectors and one 128KB sector at the top or bottom of address

space with all remaining sectors of 256KB

- Configuration 2 - Physical set of sixteen 4KB sectors and one 192KB sector at both the top and bottom of the

address space with all remaining sectors of 256KB

The combination of the sector architecture selection bits in Configuration registers support the different sector

architecture options of the SEMPER™ Flash family. See Registers on page 89 for more information.
