Patent number: 9990278Abstract: An overlaid erase block (EB) mapping scheme for a flash memory provides efficient wear-leveling and reduces mount operation latency. The overlaid EB mapping scheme maps a first type of EB onto one of a plurality of physical erase blocks, in a corresponding portion of the flash memory. The first type of EB includes a plurality of pointers. The overlaid EB mapping scheme also maps each of second and third types of EBs onto one of the physical EBs that is not mapped to the first type of EB. The second type of EBs store system management information and the third type of EBs store user data. When the flash memory is started up, the overlaid EB mapping scheme scans the corresponding portion to locate the first type of EB, locates the system EBs using the pointers, and locates the data EBs using the system management information.Type: GrantFiled: October 20, 2014Date of Patent: June 5, 2018Assignee: Cypress Semiconductor CorporationInventors: Shinsuke Okada, Sunil Atri, Hiroyuki Saito

Publication number: 20180081564Abstract: Disclosed herein are system, method, and computer program product embodiments for accessing data of a memory. A method embodiment operates by receiving one or more requests for data stored across at least a first memory area and a second memory area of a memory. The method continues with performing, by at least one processor, a wrapped read of data within a first memory area of the memory. The method then performs, by the at least one processor, a continuous read of data within a second memory area of the memory, the second memory area being adjacent to the first memory area. The continuous read starts at a first boundary of the second memory area, and is performed automatically after the wrapped read of data within the first memory area.Type: ApplicationFiled: October 12, 2017Publication date: March 22, 2018Applicant: Cypress Semiconductor CorporationInventors: Qamrul Hasan, Shinsuke Okada, Yuichi Ise, Kai Dieffenbach, Kioymatsu SHOUJI
