    • A memory storage method used in a memory storage control device for storing data cells (DC) in memory locations (ML) of a memory (MEM) is presented. The memory locations (ML) are grouped in predetermined distinct groups (S1/SN) with respective cyclically ordered group addresses (SA1/SAN). The data cells (DC) have respective cell identifiers (ID) corresponding to respective group addresses. The method includes for each data cell (DC) to be stored the steps of:

      allocating the corresponding group address (SAM) to its cell identifier (ID);
      starting with the group (SM) with the corresponding group address (SAM) and in said cyclic order allocating respective predetermined group filling levels (PV1,PV2,...) to the groups (S1/SN) and performing an iterative investigation process, each phase thereof comprising the steps of comparing an actual filling level of the group investigated with the predetermined group filling level allocated thereto, and deciding in function of the result thereof whether the data cell has to be stored in a free memory location of this group or a following group has to be investigated during a following phase of said process, the iterative process being finished when either said free memory location is found or a predetermined number of groups is investigated.
    • 在存储器(MEM)的存储单元(ML)中存储用于存储数据单元(DC)的存储器存储控制装置中使用的存储器存储方法。 存储器位置(ML)被分组在具有各个循环排序的组地址(SA1 / SAN)的预定的不同组(S1 / SN)中。 数据信元(DC)具有对应于各个组地址的各自的小区标识符(ID)。 该方法包括对于要存储的每个数据单元(DC)的步骤:将相应的组地址(SAM)分配给其小区标识符(ID); 从具有对应组地址(SAM)的组(SM)开始,并且以所述循环顺序向组(S1 / SN)分配各个预定组填充级别(PV1,PV2,...)并执行迭代调查处理, 其每个阶段包括以下步骤:将所研究的组的实际填充水平与分配给其的预定组填充水平进行比较,并且根据其结果确定数据单元是否必须存储在该组的空闲存储器位置,或 必须在所述过程的后续阶段期间研究以下组,当查找到所述空闲存储器位置或调查预定数量的组时,迭代过程完成。
