; availability of the particular block of memory. Size of that block can
; be calculates as follow:
; Let
;  Size of the block				= x
;  Size of the memory pool			= y
;  Then number of memory blocks in the pool 	= (y / x) blocks
;  Number of bits needed to represent above 	= (y / x) bits
;  Number of bytes needed to represent above	= (y / x) / 8 bytes
