Patent number: 8975185Abstract: During formation of a charge trap separation in a semiconductor device, a polymer deposition is formed in a reactor using a first chemistry. In a following step, a second chemistry can be used to etch the polymer deposition in the reactor. The same or similar second chemistry can be used in a second etching step to expose a first oxide layer in each of the cells of the semiconductor device and to form a flat upper surface. This additional etch step can also be performed by the reactor, thereby reducing the number of machines required in the formation process.Type: GrantFiled: November 26, 2012Date of Patent: March 10, 2015Assignee: Spansion, LLCInventor: Angela Tai Hui

Patent number: 8972652Abstract: A method of reducing read errors in a non-volatile memory device that result from bit-line or word-line disturb conditions generated by erase operations includes selecting a subset of a memory array for refresh after each erase operation. A pointer to the refresh target section is updated as part of the method to direct the refresh operation to the appropriate subset of the memory array. Refresh may be performed subsequent to an erase operation or concurrently therewith. By distributing the time consumed by refresh operations over many erase operations so the relative refresh time for any one erase becomes small.Type: GrantFiled: November 19, 2012Date of Patent: March 3, 2015Assignee: Spansion LLCInventors: Yong K.

Patent number: 8938655Abstract: Providing for extended data retention of flash memory devices by program state rewrite is disclosed herein. By way of example, a memory cell or group of memory cells can be evaluated to determine a program state of the cell(s). If the cell(s) is in a program state, as opposed to a natural or non-programmed state, a charge level, voltage level and/or the like can be rewritten to a default level associated with the program state, without erasing the cell(s) first. Accordingly, conventional mechanisms for refreshing cell program state that require rewriting and erasing, typically degrading storage capacity of the memory cell, can be avoided. As a result, data stored in flash memory can be refreshed in a manner that mitigates loss of memory integrity, providing substantial benefits over conventional mechanisms that can degrade memory integrity at a relatively high rate.Type: GrantFiled: December 20, 2007Date of Patent: January 20, 2015Assignee: Spansion LLCInventors: Darlene G. Hamilton, Mark W. Randolph, Don Carlos Darling, Ron Kornitz
