Memory module and method for operating a memory module

Abstract

A memory module comprises a nonvolatile memory unit ( 2 ) and a volatile memory unit ( 1 ), which are electrically coupled. The nonvolatile memory unit ( 2 ) is operable to store data permanently. The volatile memory unit ( 1 ) is operable to load the data stored in the nonvolatile memory unit ( 2 ) in order to perform an operation based on the data.

Description

technical field [0001] The present invention generally relates to memory modules including volatile memory devices and non-volatile memory devices and also to methods of operating the memory modules. Background technique [0002] Conventional volatile memory cannot store data permanently. Memory contents are lost when power is lost. In order to operate the volatile memory, means for permanently storing device parameters would be advantageous. An exemplary need to permanently store such device parameters is described below. [0003] Volatile memory consists of a large number of storage locations. Each storage unit enables the storage of small blocks of information, which are data words, bits or bytes. Each memory location can be accessed by its own address. Volatile memory may also contain regions of redundant memory cells, for example, for the purpose of replacing failed memory cells. A failed storage unit can be blocked and replaced by a redundant storage unit. [00...
