boot block


Also found in: Dictionary.

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.
The M50LPW116 has asymmetric block architecture: its array of 50 blocks is divided into one boot block of 16 KBytes, two parameter blocks of 8 KBytes, one main block of 32 KBytes, 30 main blocks of 64 KBytes and 16 parameters of 4 KBytes each.
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.
Top and bottom boot block architectures are available with the following block sizes: 1-16kB, 2-8kB, 1-32kB and 31-64kB.

7 volts and comes with both top and bottom boot block options.
When packaged with SRAM and boot block flash, NAND may offer a very viable cost per bit advantage and reasonable performance.
