`ABSTRACT
`
`-
`The memory system has one or more memory dies coupled
`to a processor or other system controller. Each die has a
`separate memory array organized into multiple memory
`blocks. The different memory blocks of each die can be
`assigned a different memory density by the end user,
`depending on the desired memory performance and/or
`memory density. The user configurable density/performance
`option can be adjusted with special read/write operations or
`a configuration register having a memory density configu
`ration bit for each memory block.
