摘要：
A method and system using a virtual lock for boot block flash are disclosed in which code from a boot block of a flash memory is executed. The boot block is hardware protected. One or more ancillary boot blocks in the flash memory are locked based on the executed code such that the ancillary boot blocks are virtually hardware locked. The ancillary boot blocks can be virtually hardware locked using a programmable technique.
