TDK Assigned Three Patents

Magnetic memory and method for controlling
TDK Corp., Tokyo, Japan, has been assigned a patent (11,257,533) developed by Shiokawa, Yohei, Tokyo, Japan, for “magnetic memory and method for controlling the same.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A magnetic memory includes a storage element including a first ferromagnetic layer, a first conductive layer which faces the first ferromagnetic layer in a first direction and extends in a second direction different from the first direction, and a first conductive part and a second conductive part which are connected to the first conductive layer at positions which sandwich the first ferromagnetic layer in the second direction when seen in the first direction, and a plurality of first switching elements which are electrically connected to the first conductive part of the storage element.”

The patent application was filed on July 6, 2020 (16/921,211).

Memory controller and memory
TDK Corp., Tokyo, Japan, has been assigned a patent (11,256,432) developed by Mukaida, Naoki, and Takubo, Kenichi, Tokyo, Japan, for “memory controller and memory system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A memory controller capable of preventing important data stored in a flash memory from being lost and maintaining the quality of a physical block. A memory controller for controlling access to a flash memory including a plurality of physical blocks, each of which includes a plurality of pages, based on a command assigned from a host system. The memory controller stores a first correspondence relationship between a logical block of a first logical region and a physical block of a first physical region in a first storage unit. The memory controller manages the first physical region in which a process of moving data saved in the physical block of the first physical region having the correspondence relationship with the logical block of the first logical region is prohibited without being based on a command for writing the data to the first logical region assigned from the host system.”

The patent application was filed on September 18, 2019 (16/574,340).

Memory controller and memory
TDK Corp., Tokyo, Japan, has been assigned a patent (11,249,895) developed by Mukaida, Naoki, and Takubo, Kenichi, Tokyo, Japan, for “memory controller and memory system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A memory controller for preventing the storage area of a flash memory being reduced is provided. The memory controller controlling access to a flash memory based on a command provided from a host system, the memory controller includes: a processor, a RAM (random access memory) and a mask ROM (read only memory) in which a first firmware is written, wherein the memory controller is configured to: perform a search for a second firmware written in the flash memory based on the first firmware at a start-up time, and write a third firmware provided from the host system in the RAM when the second firmware is not found through the search and perform an initialization based on the third firmware written in the RAM.”

The patent application was filed on September 3, 2019 (16/558,464).
