摘要： A boot method for a data control unit downloads boot information from a nonvolatile memory into a temporary buffer of a boot-activation unit. A processing unit is activated by the boot-activation unit; a boot code is executed by the processing unit; and an operating code is downloaded from the nonvolatile memory into a volatile memory through the boot-activation unit. To correct possible errors in the block of the nonvolatile memory containing information and boot codes, the boot-activation unit verifies whether the boot information downloaded into its volatile memory has a critical-error condition and activates a spare memory portion of the nonvolatile memory in presence of the critical-error condition.

摘要： A memory, particularly but not limitatively a flash memory, comprises at least one data storage area comprising a plurality of data storage locations, and an access circuitry for accessing the data storage locations for either retrieving or altering a data content thereof, depending for example on a memory user request. The memory includes at least one first user-configurable flag element and a second user-configurable flag element. Both the at least one first and the second flag elements are used by a user to set a protected state of the respective data storage area against alteration of the content of the data storage locations thereof. The protected state defined by setting the first flag element is user-removable, i.e., it can be removed by request from the user, so as to enable again the alteration of the content of the data storage area. On the contrary, the protected state defined by setting the second flag element is permanent and, once set, it cannot be removed: the data storage area becomes unalterable.
摘要翻译：存储器，特别地但不限于闪速存储器，包括至少一个包括多个数据存储位置的数据存储区域，以及用于访问数据存储位置以用于检索或更改其数据内容的访问电路，这取决于例如内存用户请求。存储器包括至少一个第一用户可配置标志元件和第二用户可配置标志元件。所述至少一个第一和第二标志元素都由用户用于设置相应数据存储区域的受保护状态以防其数据存储位置的内容的改变。通过设置第一标志元素定义的受保护状态是用户可移除的，即，可以通过来自用户的请求去除它，以便再次启用数据存储区域的内容的改变。相反，通过设置第二标志元素定义的受保护状态是永久性的，一旦设置，就不能被去除：数据存储区域变得不可更改。

摘要： A memory device implements a reading operation. The memory device includes first, second, and third memory cells; a read circuit coupled to the memory cells and operable to read first, second, and third values, respectively, from the first, second, and third memory cells; and a comparison circuit coupled to the read circuit and operable to compare the first and second values with fourth and fifth predetermined values and to generate a data-valid signal that indicates that the third value is valid if the first and second values equal the fourth and fifth values, respectively. The memory device may further include a selection circuit coupled to the read circuit and to the comparison circuit and operable to couple the third value to a data bus in response to the data-valid signal.
