Abstract: A microelectronic memory may be password access protected. A controller may maintain a register with requirements for accessing particular memory locations to initiate a security protocol. A mapping may correlate which regions within a memory array are password protected. Thus, a controller can use a register and the mapping to determine whether a particular granularity of memory is password protected, what the protection is, and what protection should be implemented. As a result, in some embodiments, a programmable password protection scheme may be utilized to control a variety of different types of accesses to particular regions of a memory array.

Abstract translation: 微电子存储器可能受密码访问保护。 控制器可以维护具有访问特定存储器位置以启动安全协议的要求的寄存器。 映射可以将存储器阵列中的哪些区域与密码保护相关联。 因此，控制器可以使用寄存器和映射来确定特定粒度的存储器是否受密码保护，保护是什么以及应该实施何种保护。 结果，在一些实施例中，可以使用可编程密码保护方案来控制对存储器阵列的特定区域的各种不同类型的访问。
