Innovative Memory Sys., Inc. v. Micron Tech., Inc.

United States Court of Appeals for the Federal Circuit

August 27, 2019, Decided

2017-2472

Opinion

 [*1014]  Prost, Chief Judge.

Innovative Memory Systems, Inc. ("IMS") appeals from the final written decision of the Patent Trial and Appeal Board ("Board") in an inter partes review filed by Micron Technology, Inc. ("Micron"). The Board concluded that the challenged claims of U.S. Patent No. 6,901,498 ("the '498 patent") were unpatentable in view of the prior art of record. For the reasons below, we affirm-in-part, reverse-in-part, vacate-in-part, and remand.

The '498 patent generally relates to non-volatile memory. A non-volatile memory, such as a flash memory, can be "divided into logical zones" in order to "reduce the size of the data structures it uses for address [**2]  translation." '498 patent col. 6 ll. 25-28. The '498 patent involves "methods to adjust the zone boundaries to accommodate defects allowed by memory test to improve card yields and to adjust boundaries in the field to extend the usable lifetime of the card." Id. col. 6 ll. 29-32. Independent claim 1 is representative and recites:

1. A memory system circuit, comprising:

a memory comprising a plurality of blocks of nonvolatile storage elements wherein the storage elements within individual ones of the blocks are simultaneously erasable, and

a controller that controls programming of data into addressed blocks, reading data from addressed blocks and erasing data from one or more of addressed blocks at a time, wherein the memory is organized into logical zones each comprised of one or more blocks for address translation, and wherein the correspondence of blocks to zones is adjustable by controller.

Id. col. 12 ll. 56-67.
