摘要： An SRAM memory device including a plurality of memory cells arranged in a plurality of rows and a plurality of columns; each row of memory cells is adapted to store a RAM word; the RAM word includes a corresponding data word, a corresponding ECC word to be used for error detection and correction purposes and a corresponding applicative word to be used during debugging operations. The SRAM memory device further includes a configurable port adapted to receive a RAM word and to program corresponding memory cells of a selected row based on the received RAM word during a writing access of the SRAM memory device. The SRAM memory device further includes a memory controller unit including circuitry for selectively configuring the configurable port in one among a plurality of modes. The plurality of modes includes a first mode, wherein the configurable port is configured in such a way to disable the programming of the data word and of the corresponding ECC word of the received RAM word and at the same time enable the programming of the applicative word of the received RAM word during the writing access. The plurality of modes includes a second mode, wherein the configurable port is configured in such a way to disable the programming of the applicative word of the received RAM word and at the same time enable the programming of the data word and of the corresponding ECC word of the received RAM word during the writing access.
摘要翻译：一种SRAM存储器件，包括以多行和多列布置的多个存储单元; 每行存储单元适于存储RAM字; RAM字包括相应的数据字，用于错误检测和校正目的的相应ECC字以及在调试操作期间使用的对应字。 SRAM存储器件还包括可配置端口，其适于在SRAM存储器件的写入访问期间基于所接收的RAM字来接收RAM字并编程所选行的相应存储器单元。 SRAM存储器装置还包括存储器控制器单元，其包括用于在多个模式之一中选择性地配置可配置端口的电路。多个模式包括第一模式，其中可配置端口被配置为禁止数据字和所接收的RAM字的相应ECC字的编程，并且同时使得应用字的编程在写入访问期间接收到的RAM字。多个模式包括第二模式，其中可配置端口被配置为禁止所接收的RAM字的应用字的编程，并且同时使得能够对数据字和对应的ECC字进行编程在写入访问期间接收到的RAM字。
