Patent application number | Description | Published |
20120311406 | DATA PROTECTION ACROSS MULTIPLE MEMORY BLOCKS - Data protection across multiple memory blocks can include writing a first portion of a codeword in a first location of a first memory block and writing a second portion of the codeword in a second location of a second memory block. The second location can be different than the first location with respect to the second and the first memory blocks. | 12-06-2012 |
20140160845 | SETTING A DEFAULT READ SIGNAL BASED ON ERROR CORRECTION - The present disclosure includes apparatuses and methods related to setting a default read signal based on error correction. A number of methods can include reading a page of data from a group of memory cells with a first discrete read signal and error correcting at least one codeword of the page of data as read with the first discrete read signal. Methods can include reading a page of data from the group of memory cells with a second discrete read signal different than the first discrete read signal and error correcting at least one codeword of the page of data as read with the second discrete read signal. One of the first and the second discrete read signals can be set as a default read signal based at least in part on the respective error corrections. | 06-12-2014 |
20140325316 | DATA PROTECTION ACROSS MULTIPLE MEMORY BLOCKS - Data protection across multiple memory blocks can include writing a first portion of a codeword in a first location of a first memory block and writing a second portion of the codeword in a second location of a second memory block. The second location can be different than the first location with respect to the second and the first memory blocks. | 10-30-2014 |
20150135027 | DETERMINING AN AGE OF DATA STORED IN MEMORY - The present disclosure includes apparatuses and methods for determining an age of data stored in memory. A number of embodiments include determining a sensing voltage that results in a particular error rate being associated with a sense operation performed on a memory using the sensing voltage, determining a difference between the determined sensing voltage and a program verify voltage associated with the memory, and determining an age of data stored in the memory based on the determined difference. | 05-14-2015 |
20160110257 | SETTING A DEFAULT READ SIGNAL BASED ON ERROR CORRECTION - The present disclosure includes apparatuses and methods related to setting a default read signal based on error correction. A number of methods can include reading a page of data from a group of memory cells with a first discrete read signal and error correcting at least one codeword of the page of data as read with the first discrete read signal. Methods can include reading a page of data from the group of memory cells with a second discrete read signal different than the first discrete read signal and error correcting at least one codeword of the page of data as read with the second discrete read signal. One of the first and the second discrete read signals can be set as a default read signal based at least in part on the respective error corrections. | 04-21-2016 |
20160117216 | TEMPERATURE RELATED ERROR MANAGEMENT - Apparatuses and methods for temperature related error management are described. One or more apparatuses for temperature related error management can include an array of memory cells and a write temperature indicator appended to at least one predetermined number of bytes of the stored data in the array of memory cells. The apparatuses can include a controller configured to determine a numerical temperature difference between the write temperature indicator and a read temperature indicator and determine, from stored operations, an error management operation for the stored data based, at least in part, on comparison of the numerical temperature difference to a temperature difference threshold. | 04-28-2016 |
20160117272 | PROGRAMMING INTERRUPTION MANAGEMENT - The present disclosure is related to programming interruption management. An apparatus can be configured to detect an interruption during a programming operation and modify the programming operation to program a portion of the memory array to an uncorrectable state in response to detecting the interruption. | 04-28-2016 |
20160118129 | READ VOLTAGE ADJUSTMENT - The present disclosure includes apparatuses and methods related to adjusting read voltages of charge-trapping flash memory. An example embodiment apparatus can include a memory array and a controller coupled to the memory array. The controller is configured to adjust a read voltage used to access a portion of the memory array based on a length of time since a last WRITE operation to the portion. | 04-28-2016 |
20160118143 | THRESHOLD VOLTAGE MARGIN ANALYSIS - The present disclosure is related to a threshold voltage margin analysis. An example embodiment apparatus can include a memory and a controller coupled to the memory. The controller is configured to determine a previous power loss of a memory to be an asynchronous power loss, and identify a portion of the memory last subject to programming operations during the determined asynchronous power loss. The controller is further configured to perform a threshold voltage (Vt) margin analysis on the portion of the memory responsive to the determined asynchronous power loss. | 04-28-2016 |
