boot block

(operating system)
A program at some fixed location on a hard disk, floppy disk or other media, which is loaded when the computer is turned on or rebooted and which controls the next phase of loading the actual operating system. The loading and execution of the boot block is usually controlled by firmware in ROM or PROM.

Additionally, DiskOnChip G4's internal XIP boot block eliminates the cost associated with a separate NOR flash-based boot device.
Further cost benefits are derived from the efficient architecture of DiskOnChip H1, which includes a boot block that can replace expensive NOR flash alternatives.
Mobile DiskOnChip features high performance, unmatched reliability and an ultra thin controller and is equipped with a built-in boot block enabling it to completely replace legacy NOR devices within a smaller physical space and decrease overall expenditure on memory.

When packaged with SRAM and boot block flash, NAND may offer a very viable cost per bit advantage and reasonable performance.
With a built-in eXecute In Place (XIP) boot block, Mobile DiskOnChip can be used as the only non-volatile memory (NVM) on board.
As a result, Atmel's 4-megabit LPC Flash is the only LPC Flash in the market that utilizes a 32-kilobyte boot block, whereas other 4-megabit LPC Flash devices incorporate a 64-kilobyte boot block.
13 micron MLC NAND flash, an ultra thin controller and an execute in place (XIP) boot block.
The BIOS boot block addresses the TPM chip that verifies the BIOS authenticity itself.
The Flash memories feature a lockable boot block that enables critical startup software modules to be protected, and for the 2-Mbyte version a dual-plane architecture supporting read-while-write.
These 32-Mbit 3V Flash memories are organized as 4-Mbit x 8-bit or 2-Mbit x 16-bit, and also include a boot block.
