Abstract
A flash translation layer method, system, and computer program product, include performing a virtualization of a meta-flash translation layer by: instantiating a range in a NAND chip comprising the number of free blocks using a meta-FTL to create a compatible range of blocks for a type of a feature and a flash characteristic of a translation table if a number of free blocks are available in the NAND chip and instantiating a second range in the NAND chip comprising a second number of free blocks using the meta-FTL to create a second compatible range of blocks for a second type of feature and a second flash characteristic of the translation table, and dynamically programming data on the fly based on an input requirement of a request into the range and the second range.
